(L86 LSW) The L86A1 LSW ("Light Support Weapon") is a magazine-fed squad automatic weapon originally intended to provide fire support at a fireteam level. Its barrel is longer than the L85A1 and has a shorter handguard with a support stock with lightening holes protruding from the front holding a bipod. The stock has a shoulder strap and rear vertical grip. The weapon is otherwise identical to the L85 version on which it is based, and the same 30-round magazines and sighting systems are used. Like the L85 rifle, it has a selector on the left side behind the magazine housing, enabling either single shots or automatic fire. The bolt and trigger system are modified, so the gun can be fired from open bolt. The increased barrel length, bipod and the optical performance of the SUSAT give the weapon excellent accuracy, increased muzzle velocity and further stabilizes the bullet, giving a greater effective range. From its inception, the L86 was a target of criticism on much the same basis as the L85. The LSW has the additional issue (shared by any light support weapon derived from a rifle, for example the heavy-barrel FN FAL) of its inability to deliver sustained automatic fire as it lacks a quick-change barrel, and belt feed. For a time, the primary use of the LSW shifted to that of a marksman's weapon within many infantry sections, capable of providing precision fire at ranges of over 600 m;[34] however, it was replaced in this role by the Rifle, 7.62 mm L129A1.[35] The role of a light support weapon is instead filled by the L110A2 Light Machine Gun FN Minimi, which is a belt fed weapon with a quick-change barrel. The L86A1 was upgraded to the L86A2 at the same time as L85A1 rifles were upgraded to L85A2 standards, undergoing the same set of modifications. (SA80) The SA80 is a British family of 5.56×45mm NATO small arms, all of which are selective fire, gas-operated assault rifles. The L85 rifle variant of the SA80 family has been the standard issue service rifle of the British Armed Forces since 1987, replacing the L1A1 variant of the FN FAL. The first prototypes were created in 1976, with production ending in 1994. The A1 variant was significantly upgraded in the early 2000s by Heckler & Koch as the SA80A2 and remains in service as of 2017. In mid-2016 a prototype A3 variant was showcased which further improved on the weapon and is reportedly being considered to extend the out of service date beyond 2025. The remainder of the SA80 family comprises the L86 Light Support Weapon, the short-barrelled L22 carbine and the L98 Cadet rifle. The SA80 was the last in a long line of British weapons (including the Lee–Enfield family) to come from the Royal Small Arms Factory, the national arms development and production facility at Enfield Lock. (History) [Development] The system's history dates back to the late 1940s, when an ambitious programme to develop a new cartridge and new class of rifle was launched in the United Kingdom based on combat experience drawn from World War II. Two 7mm prototypes were built in a bullpup configuration, designated the EM-1 and EM-2. When NATO adopted the 7.62×51mm NATO rifle cartridge as the standard calibre for its service rifles, further development of these rifles was discontinued (the British Army chose to adopt the 7.62 mm L1A1 SLR semi-automatic rifle, which is a licence-built version of the Belgian FN FAL). (Production) After receiving feedback from users and incorporating the various design changes requested, including adapting the rifle for use with the heavier Belgian SS109 version of the 5.56×45mm round and improving reliability, the weapon system was accepted into service with the British Armed Forces in 1985 as the SA80. The SA80 family originally consisted of the L85A1 IW (Individual Weapon) and the L86A1 LSW (Light Support Weapon). The first rifle was issued on 2 October 1985 to Sergeant Gary Gavin, (Variants) There are four main variants that make up the SA80 family: the L85 IW Rifle, the L86 Light Support Weapon, the L22 Carbine and the L98 Cadet rifle. The family has currently consists of two major models, A1 variants being the first issue weapons, and A2 distinguishing weapons which have undergone H&K upgrades. The L and A in the weapon title mean Number and Mark I.e. Number 85 Mark 1 = L85A1.

(Beretta 93R) The Beretta 93R is a selective-fire machine pistol, designed and manufactured by Italian firearms manufacturer Beretta in the 1970s for police and military use, that is derived from their semi-automatic Beretta 92. The "R" stands for Raffica, which is Italian for "volley", "flurry", or "burst" (sometimes spoken "R" as "Rapid" in English). (History) The Beretta 93R was designed to be used by the Italian counter-terrorism forces of Nucleo Operativo Centrale di Sicurezza and Gruppo di Intervento Speciale but was also adopted by other police and military forces who required a concealable weapon with rapid fire capabilities.[2][3] The pistol is a development of the Beretta 92 design. (Mechanics) The Beretta 93R is mechanically similar to the Beretta 92. It can be selected to fire either a three round burst or single fire. A selector switch enables the operator to alternate between the two firing modes. The pistol is fitted with a vertical foregrip at the front end of the trigger guard to provide better stability when firing.[3] A folding steel buttstock can be attached at the heel of the grip.[4] The 93R is considered difficult to control when being repeatedly fired in burst mode because of the 1,100-round-per-minute firing rate.

KRISS Vector 45 ACP The Semi-Automatic KRISS Vector CRB submachine gun d...

(KRISS Vector) The KRISS Vector[4] series is a family of weapons based upon the parent submachine gun design developed by KRISS USA, formerly Transformational Defense Industries (TDI). They use an unconventional delayed blowback system combined with in-line design to reduce perceived recoil and muzzle climb. (History) In the spring of 2007, TDI announced the Kriss Super V submachine gun. It was an experimental weapon under advanced stages of development at that time. The name Kriss comes from a Southeast Asian dagger with a flame-shaped blade.[5] The second generation prototype of the KRISS Vector called the K10 was announced at SHOT Show 2011.[6] It is a slightly more compact version of the Vector that is based on the same Super V system. The main difference is the use of a telescopic stock that collapses into the upper receiver rather than the earlier folding stock. The charging handle operates downward instead of horizontally. The K10 was not displayed after SHOT Show 2013 and its status is unknown and likely has been canceled. KRISS announced the "Gen II" versions of the original Vector models in 2015. It features a redesigned pistol grip, safety selector, and compatibility with a new 9mm lower were announced. It appears to have replaced the K10 prototypes. (Design) The KRISS Vector uses the KRISS Super V Recoil Mitigation System, that is an articulated mechanism which allows the bolt and an inertia block to move downward into a recess behind the magazine well.[8] The theory is that at the end of this travel, the energy is transmitted downward rather than rearward, thus reducing the felt recoil. When fired, the barrel axis is in line with the shoulder as in the M16 rifle, but also in line with the shooter's hand. This is intended to reduce muzzle climb when combined with the off-axis bolt travel, though it also greatly raises the sight line in comparison to the bore axis. The initial prototype model by TDI achieved a rate of fire of 1,500 rounds per minute (RPM), though this was bought down to around 1,200 rounds per minute (RPM) on the production models. In a similar manner to the AR-15 rifle, that is secured together with four push pins; the KRISS Vector is split into two major assemblies. Due to the weapon's unusual layout, the lower contains the action, charging handle, magazine well and barrel, while the upper contains the ejection port, rail system, pistol grip and fire control components, as well as the stock for configurations that have one. This modular design allows for toolless caliber conversions by swapping out only the lower. The Vector's safety is ambidextrous (as well as the fire mode selector on the auto trigger pack) while the ejection port, charging handle, bolt release catch and magazine release are not, and are only available in a right-handed configuration.

(IWI Galil ARM) The Galil is a family of Israeli small arms designed by Yisrael Galil and Yaacov Lior in the late 1960s and produced by Israel Military Industries (IMI) (IMI privatized their small arms division, now called IWI) of Ramat HaSharon. The rifle design borrows heavily from the RK-62 and has a modified gas diversion system similar to the RK-62 to reduce the recoil of the rifle making it easier to fire especially in automatic mode.[2] The weapon system consists of a line chambered for the intermediate 5.56×45mm NATO caliber with either the M193 or SS109 ball cartridge and several models designed for use with the 7.62×51mm NATO rifle round. It is named after one of its inventors, Yisrael Galil. The Galil series of weapons is in use with military and police forces in over 25 countries. There are four basic configurations of the Galil: the standard-length rifle, a carbine variant known as the SAR, a compact MAR version, and an ARM light machine gun. A modernized version of the Galil is currently in production in multiple calibers, called the Galil ACE. (History) In the late 1950s, the Israel Defense Forces adopted the FN FAL battle rifle chambered for the 7.62×51mm cartridge. Two models were fielded: the "Aleph" individual weapon and the "Bet" squad automatic weapon. The FAL first saw major combat with the Israelis during the Six-Day War in 1967. Although Israel won decisive victories, the FAL showed its limitations in IDF service; the common complaint was that the sand and dusty conditions caused the weapon's malfunction, but this was later attributed to the lack of maintenance given by IDF conscripts. Furthermore, it was a long and bulky weapon. Its length and malfunctions became so much of an issue that during the 1973 Yom Kippur War, some soldiers armed themselves with an Uzi submachine gun with an extended barrel.[3][4] During the Six-Day War, the Israelis captured thousands of AK-47 assault rifles and evaluated them. The rifle proved far more reliable and controllable than the FAL, and the required maintenance was low enough so that the conscripted troops would not require more stringent regulations of the weapon's care. Because of this, the IDF began the process of procuring a new automatic rifle that would offer the same benefits of low-maintenance as the AK-47 but with the accuracy of the M16 and FAL. Several weapons were submitted for the lucrative deal of becoming the Israeli Army's standard-issue assault rifle; America offered the M16A1 and Stoner 63 series and Germany offered the HK 33. The AK-47 design was also considered, but difficulty in procurement limited its viability. One indigenous design was offered by Uziel Gal, creator of the Uzi submachine gun, but was ultimately found too complex and unreliable for adoption. (Design details) [Operating mechanism] The Galil series of rifles are selective fire weapons operated by a Kalashnikov-pattern gas-driven piston system with no regulator. The weapon is locked with a rotary bolt with two locking lugs that lock into recesses milled into the receiver.

(Lockheed U-2) The Lockheed U-2, nicknamed "Dragon Lady", is an American single-jet engine, ultra-high altitude reconnaissance aircraft operated by the United States Air Force (USAF) and previously flown by the Central Intelligence Agency (CIA). It provides day and night, high-altitude (70,000 feet; 21,000 m), all-weather intelligence gathering.[2] The U-2 has also been used for electronic sensor research, satellite calibration, and communications purposes. Early versions of the U-2 were involved in several events through the Cold War, being flown over the Soviet Union, China, Vietnam, and Cuba. In 1960, Gary Powers was shot down in a CIA U-2A over the Soviet Union by a surface-to-air missile (SAM). Another U-2, piloted by Major Rudolf Anderson, Jr., was lost in a similar fashion during the Cuban Missile Crisis of 1962. The U-2 is one of a handful of aircraft types to have served the USAF for over 50 years, one notable example being the Boeing B-52. The newest models (TR-1, U-2R, U-2S) entered service in the 1980s. The current model, the U-2S, received its most recent technical upgrade in 2012. They have taken part in post–Cold War conflicts in Afghanistan and Iraq, and supported several multinational NATO operations. (Development) Background After World War II, the U.S. military desired better strategic aerial reconnaissance to help determine Soviet capabilities and intentions. Into the 1950s, the best intelligence the American government had on facilities deep inside the Soviet Union were German Luftwaffe photographs taken during the war of territory west of the Ural Mountains, so overflights to take aerial photographs of the Soviet Union began. After 1950, Soviet air defenses aggressively attacked all aircraft near the country's borders—sometimes even those over Japanese airspace—and the existing reconnaissance aircraft, primarily bombers converted for reconnaissance duty such as the Boeing RB-47, were vulnerable to anti-aircraft artillery, missiles, and fighters. Richard Leghorn of the USAF suggested that an aircraft that could fly at 60,000 feet (18,300 m) should be safe from the MiG-17, the Soviet Union's best interceptor, which could barely reach 45,000 feet (13,700 m). He and others believed that Soviet radar, which used American equipment provided during the war, could not track aircraft above 65,000 feet (19,800 m).[3] The highest-flying aircraft available to America and its allies at the time was the English Electric Canberra, which could reach 48,000 feet (14,600 m). The British had already produced the PR3 photo-reconnaissance variant, but the USAF asked for English Electric's help to further modify the Martin B-57 (the American licensed version of the Canberra) with long, narrow wings, new engines, and a lighter-than-normal airframe to reach 67,000 feet (20,400 m). Air Research and Development Command mandated design changes that made the aircraft more durable for combat, but the resulting RB-57D aircraft of 1955 could only reach 64,000 feet (19,500 m). The Soviet Union, unlike the United States and Britain, had improved radar technology after the war, and could track aircraft above 65,000 feet (Lockheed proposal) It was thought that an aircraft that could fly at 70,000 feet (21,300 m) would be beyond the reach of Soviet fighters, missiles, and radar.[5] Another USAF officer, John Seaberg, wrote a request for proposal in 1953 for an aircraft that could reach 70,000 feet (21,300 m) over a target with 1,500 nmi (1,700 mi; 2,800 km) of operational radius. The USAF decided to solicit designs only from smaller aircraft companies that could give the project more attention.[6] Under the code name "Bald Eagle", it gave contracts[7] to Bell Aircraft, Martin Aircraft, and Fairchild Engine and Airplane to develop proposals for the new reconnaissance aircraft. Officials at Lockheed Aircraft Corporation heard about the project and decided to submit an unsolicited proposal. To save weight and increase altitude, Lockheed executive John Carter suggested that the design eliminate landing gear and avoid attempting to meet combat load factors for the airframe. The company asked Clarence "Kelly" Johnson to come up with such a design. Johnson was Lockheed's best aeronautical engineer,[8] responsible for the P-38 and the P-80. He was also known for completing projects ahead of schedule, working in a separate division of the company, informally called the Skunk Wor

(Heckler & Koch USP) The USP (Universelle Selbstladepistole or "universal self-loading pistol") is a semi-automatic pistol developed in Germany by Heckler & Koch GmbH (H&K) of Oberndorf am Neckar as a replacement for the P7 series of handguns. (History) Design work on a new family of pistols commenced in September 1989 focused primarily on the United States commercial and law enforcement markets. USP prototypes participated in rigorous testing alongside H&K's entry in the Offensive Handgun Weapon System (OHWS) program requested by the U.S. Special Operations Command (USSOCOM) and which would later result in the Mk 23 Mod 0.[3] The USP prototypes were then refined in 1992, based on input from the OHWS trials, and the design was finalized in December of the same year. The USP was formally introduced in January 1993[3] with the USP40 model (the base version) chambered for the increasingly popular .40 S&W cartridge, followed soon by the USP9 (using the 9×19mm Parabellum cartridge), and in May 1995—the USP45 (caliber .45 ACP).[3] In contrast to the ambitious and innovative P7, P9S, and VP70Z designs, the USP uses a more conventional Browning-style cam-locked action, similar to that used in the Hi-Power - but with a polymer frame. (Design details) The USP is a semi-automatic pistol with a mechanically locked breech using the short recoil method of operation. This rather conventional lock-up system has a large rectangular lug over the barrel’s chamber that rides into and engages the ejection port cut-out in the slide. When a cartridge is fired, pressures generated by the ignited powder drive the cartridge casing back against the breech face on the slide, driving back both the barrel and slide as they remain locked together in the manner described above. After 3 mm (0.12 in) of unrestricted rearward travel, the projectile has left the barrel and gas pressures have dropped to a safe level. A shaped lug on the underside of the barrel chamber comes into contact with a hooked locking block at the end of the steel recoil spring guide rod, lowering the rear end of the barrel and stopping the barrel's rearward movement. The recoil spring assembly is held in place by the slide stop lever’s axis pin and a round cut-out at the front of the slide. For enhanced reliability in high-dust environments, the locking surface on the front top of the barrel’s locking lug is tapered with a forward slope. This tapered surface produces a camming action which assists in positive lock-up in the presence of heavy fouling and debris. In this way, the USP shares many design features with the M1911 pistol, although apparently updated for easier operation.

FN Five-seven, trademarked as the Five-seveN, is a semi-automatic pistol...

(FN Five-seven) The FN Five-seven, trademarked as the Five-seveN, is a semi-automatic pistol designed and manufactured by Fabrique Nationale d’Armes de Guerre-Herstal (FN Herstal) in Belgium.[8] The pistol is named for its 5.7-mm (.224 in) bullet diameter, and the trademark capitalization style is intended to emphasize the manufacturer's initials—FN.[13] The Five-seven pistol was developed in conjunction with the FN P90 personal defense weapon and the FN 5.7×28mm cartridge.[14] The P90 was introduced in 1990, and the Five-seven was introduced in 1998 as a pistol using the same 5.7×28mm ammunition.[7] Developed as a companion pistol to the P90, the Five-seven shares many of its design features: it is a lightweight polymer-based weapon with a large magazine capacity, ambidextrous controls, low recoil, and the ability to penetrate body armor when using certain cartridge types.[15] Sales of the Five-seven were originally restricted by FN to military and law enforcement customers, but since 2004, the pistol has also been offered to civilian shooters for personal protection, target shooting, and similar uses.[16][17] Although offered only with sporting ammunition, the Five-seven's introduction to civilian shooters was met with vocal opposition from gun control organizations such as the Brady Campaign, and the pistol has been subject to ongoing controversy in the United States.[18][19] The Five-seven is currently in service with military and police forces in over 40 nations, including Canada, France, Greece, India, Poland, Spain, and the United States.[20] In the United States, the Five-seven is in use with numerous law enforcement agencies, including the U.S. Secret Service.[13][21] In the years since the pistol's introduction to the civilian market in the United States, it has also become increasingly popular with civilian shooters (History) [Development[ The Five-seven pistol and its 5.7×28mm ammunition were developed by FN Herstal in response to NATO requests for a replacement for the 9×19mm Parabellum cartridge and associated pistols and submachine guns.[1] NATO called for two types of weapons chambered for a new cartridge—one a shoulder-fired weapon, and the other a handheld weapon.[1] According to NATO, these new weapons, termed personal defense weapons (PDWs), were to provide "personal protection in last-resort situations when the user is directly endangered by the enemy [...]."[1] In 1989, NATO published document D/296, outlining a number of preliminary specifications for these weapons: The new cartridge was to have greater range, accuracy, and terminal performance than the 9×19mm cartridge.[1] Additionally, it was to be capable of penetrating certain types of body armor.[1] The shoulder-fired personal defense weapon was to weigh less than 3 kg (6.6 lb), with a magazine capacity of at least 20 rounds.[1] The handheld personal defense weapon (pistol) was to weigh less than 1 kg (2.2 lb), although a weight of 700 g (1.5 lb) was deemed desirable; it was to have a magazine capacity of no fewer than 20 rounds.[1] Both weapons were to be sufficiently compact to be carried hands-free on the user's person at all times, whether in the cab of a vehicle or the cockpit of an aircraft, and were to perform effectively in all environments and weather conditions.[1] FN Herstal was the first small arms manufacturer to respond to NATO's requirement; FN started by developing a shoulder-fired personal defense weapon, the FN P90, along with a small caliber, high velocity 5.7×28mm cartridge type.[1] The original 5.7×28mm cartridge, called the SS90, went into production with the P90 in 1990.[23] This cartridge type was discontinued in 1993, and replaced with the 5.7×28mm SS190, which used a heavier and slightly shorter projectile weighing 2.0 g (31 grains).[6][23] The reduced length of the SS190 projectile allowed it to be used more conveniently in the Five-seven, which was under development at that time. In 1993, Jean-Louis Gathoye of FN filed a United States patent application for a delayed blowback operating system intended for the Five-seven pistol, and U.S. Patent 5,347,912 ("Elements for decelerating the recoil of the moving parts of a fire arm") was received the following year.[6][24] In 1995,

Heckler & Koch MP7A1 with a suppressor, extended magazine and Elcan refl...

(Heckler & Koch MP7) The Heckler & Koch MP7 (Maschinenpistole 7) is a German Personal Defence Weapon (PDW) designed and manufactured by Heckler & Koch (H&K) and chambered for the HK 4.6×30mm cartridge. It was designed with the new cartridge to meet NATO requirements published in 1989, as these requirements call for a personal defense weapon (PDW) class firearm, with a greater ability to penetrate body armor than current weapons limited to conventional pistol cartridges. The MP7 went into production in 2001. It is a direct rival to the FN P90, also developed in response to NATO's requirement. The weapon has been revised since its introduction and the latest production variants are the MP7A1 and MP7A2. The proliferation of high-quality body armor has begun to make guns that fire pistol ammunition (such as Heckler & Koch's earlier MP5 submachine gun or USP pistol) ineffective. In response to this trend, Heckler & Koch designed the MP7 (along with the now cancelled UCP pistol, which uses the same ammunition) to penetrate body armor while being small enough to be used in place of either a pistol or a submachine gun. (Design details) The MP7 uses a short-stroke piston gas system as used on H&K's G36 and HK416 assault rifles, in place of a blowback system traditionally seen on sub-machine guns including those by H&K.[12] The 4.6×30mm ammunition is exclusive to the gun and offers low recoil.[8][9] This ammunition is unique among submachine guns in that the bullet is made almost entirely of a hardened steel penetrator instead of softer copper or lead. The MP7 allows a conventional 20-round, 30-round or 40-round box magazine to be fitted within the pistol grip (the 20-round magazine being comparable in size to a 15-round 9×19mm magazine, while the 40-round magazine compares to a 30-round 9×19mm magazine). It features an ambidextrous fire selector, bolt catch lever and magazine release. It has an extendable stock and a folding front grip; it can be fired either one-handed or two-handed.[8][9] It is compact and light, due to the use of polymers in its construction. The MP7 has a cyclic rate of fire of 950 rounds per minute (RPM). (Ammunition) The MP7's specially designed armour piercing (AP) high velocity rounds consist of either copper plated solid steel (DM11), alloy plated steel jacket (DM21) or copper-alloy-jacketed lead core projectiles (Fiocchi FMJ ZP). Standard AP high velocity DM11 (Ultimate Combat) round with a 2.0 g (31 gr) projectile has a muzzle velocity of 720 m/s (2,362 ft/s) and has a muzzle energy of 506 J (373 ft-lbf).[13] The DM11 round penetrates the NATO CRISAT target (20 layers of kevlar with 1.6 mm titanium backing) even at 200 m.[14] The round has a small diameter, allowing for redoubling pentration capability and high capacity in a very small magazine. (Accessories) The MP7 features a full-length, top-mounted Picatinny rail that comes as standard with folding fore and rear iron sights attached. When the sights are folded flat, they resemble Patridge style open sights. Folded up, they feature aperture sights. The sights can easily be removed by loosening a single screw and lifting them off. It can fit additional rails on the sides of the barrel, which allow it to mount commercial optical sights (telescopic and red dot sights), laser aiming modules (LAM), and tactical flashlights. It can also accept a suppressor, and its tailor-made suppressor does not interfere with its accuracy or rate of fire.

Sea Hawk Helicopter Launches Hellfire Missile During SINKEX

(Sikorsky SH-60 Seahawk) The Sikorsky SH-60/MH-60 Seahawk (or Sea Hawk) is a twin turboshaft engine, multi-mission United States Navy helicopter based on the United States Army UH-60 Black Hawk and a member of the Sikorsky S-70 family. The most significant airframe modification is a hinged tail to reduce its footprint aboard ships. The U.S. Navy uses the H-60 airframe under the model designations SH-60B, SH-60F, HH-60H, MH-60R, and MH-60S. Able to deploy aboard any air-capable frigate, destroyer, cruiser, fast combat support ship, amphibious assault ship, or aircraft carrier, the Seahawk can handle anti-submarine warfare (ASW), anti-surface warfare (ASUW), naval special warfare (NSW) insertion, search and rescue (SAR), combat search and rescue (CSAR), vertical replenishment (VERTREP), and medical evacuation (MEDEVAC). All Navy H-60s carry a rescue hoist for SAR/CSAR missions. (Design and development) [Origins] During the 1970s, the U.S. Navy began looking for a new helicopter to replace the Kaman SH-2 Seasprite.[3] The SH-2 Seasprite was used by the Navy as its platform for the Light Airborne Multi-Purpose System (LAMPS) Mark I avionics suite for maritime warfare and a secondary search and rescue capability. Advances in sensor and avionic technology lead to the LAMPS Mk II suite, but the SH-2 was not large enough to carry the Navy's required equipment. In the mid-1970s, the Army evaluated the Sikorsky YUH-60 and Boeing-Vertol YUH-61 for its Utility Tactical Transport Aircraft System (UTTAS) competition.[4] The Navy based its requirements on the Army's UTTAS specification to decrease costs from commonality.[3] Sikorsky and Boeing-Vertol submitted proposals for Navy versions of their Army UTTAS helicopters in April 1977 for review. The Navy also looked at helicopters being produced by Bell, Kaman, Westland and MBB, but these were too small for the mission. In early 1978 the Navy selected Sikorsky's S-70B design,[3] which was designated "SH-60B Seahawk". (SH-60B Seahawk) The SH-60B maintained 83% commonality with the UH-60A.[5] The main changes were corrosion protection, more powerful T700 engines, single-stage oleo main landing gear, removal of the left side door, adding two weapon pylons, and shifting the tail landing gear 13 feet (3.96 m) forward to reduce the footprint for shipboard landing. Other changes included larger fuel cells, an electric blade folding system, folding horizontal stabilators for storage, and adding a 25-tube pneumatic sonobuoy launcher on the left side.[6] An emergency flotation system was originally installed in the stub wing fairings of the main landing gear; however, it was found to be impractical and possibly impede emergency egress, and thus was subsequently removed.[citation needed] Five YSH-60B Seahawk LAMPS III prototypes were ordered. The first YSH-60B flight occurred on 12 December 1979. The first production SH-60B made its first flight on 11 February 1983. The SH-60B entered operational service in 1984 with first operational deployment in 1985. The SH-60B is deployed primarily aboard frigates, destroyers, and cruisers. The primary missions of the SH-60B are surface warfare and anti-submarine warfare. It carries a complex system of sensors including a towed Magnetic Anomaly Detector (MAD) and air-launched sonobuoys. Other sensors include the APS-124 search radar, ALQ-142 ESM system and optional nose-mounted forward looking infrared (FLIR) turret. Munitions carried include the Mk 46, Mk 50, or Mk 54 torpedo, AGM-114 Hellfire missile, and a single cabin-door-mounted M60D/M240 7.62 mm (0.30 in) machine gun or GAU-16 .50 in (12.7 mm) machine gun. A standard crew for a SH-60B is one pilot, one ATO/Co-Pilot (Airborne Tactical Officer), and an enlisted aviation warfare systems operator (sensor operator). The U.S. Navy operated the SH-60B in Helicopter Anti-Submarine Squadron, Light (HSL) squadrons. All HSL squadrons were redesignated Helicopter Maritime Strike (HSM) squadrons and transitioned to the MH-60R between 2006 and 2015. U.S. Navy SH-60B landing on USS Abraham Lincoln.

Heckler & Koch MP5 (from German: Maschinen pistole 5, meaning Submachine...

(Heckler & Koch MP5) The Heckler & Koch MP5 (from German: Maschinenpistole 5, meaning Submachine gun 5) is a 9mm submachine gun of German design, developed in the 1960s by a team of engineers from the German small arms manufacturer Heckler & Koch GmbH (H&K) of Oberndorf am Neckar. There are over 100 variants of the MP5,[3] including some semi-automatic versions. The MP5 is one of the most widely used submachine guns in the world,[4] having been adopted by 40 nations and numerous military, law enforcement, intelligence, and security organizations.[2] It is widely used by SWAT teams in North America. In 1999, Heckler & Koch developed the Heckler & Koch UMP, the MP5's successor;[5] both are available as of 2017. (History) Heckler & Koch, encouraged by the success of the G3 automatic rifle, developed a family of small arms consisting of four types of firearms all based on a common G3 design layout and operating principle. The first type was chambered for 7.62×51mm NATO, the second for the 7.62×39mm M43 round, the third for the intermediate 5.56×45mm NATO caliber, and the fourth type for the 9×19mm Parabellum pistol cartridge. The MP5 was created within the fourth group of firearms and was initially known as the HK54.[6] Work on the MP5 began in 1964 and two years later it was adopted by the German Federal Police, border guard and army special forces.[6] In 1980, the MP5 achieved iconic status as a result of its use on live television by SAS commandos in Operation Nimrod, where they stormed the Iranian Embassy in London, rescuing hostages and killing five terrorists.[7] The MP5 became a mainstay of SWAT units of law enforcement agencies in the United States since then. However, in the late 1990s, as a result of the North Hollywood shootout, police special response teams have supplanted some MP5s with AR-15-based assault rifles.[8] The MP5 is manufactured under license in several nations including Greece (formerly at EBO – Hellenic Arms Industry, currently at EAS – Hellenic Defense Systems), Iran (Defense Industries Organization), Mexico (SEDENA), Pakistan (Pakistan Ordnance Factories), Saudi Arabia, Sudan (Military Industry Corporation), Turkey (MKEK), and the United Kingdom (initially at Royal Ordnance, later diverted to Heckler & Koch Great Britain). (Design details) The primary version of the MP5 family is the MP5A2, which is a lightweight, air-cooled, selective fire delayed blowback operated 9×19mm Parabellum weapon with a roller-delayed bolt. It fires from a closed bolt (bolt forward) position.[10] The fixed, free floating, cold hammer-forged barrel has 6 right-hand grooves with a 1 in 250 mm (1:10 in) rifling twist rate and is pressed and pinned into the receiver. (Features) The first MP5 models used a double-column straight box magazine, but since 1977, slightly curved, steel magazines are used with a 15-round capacity (weighing 0.12 kg) or a 30-round capacity (0.17 kg empty).[11] The adjustable iron sights (closed type) consist of a rotating rear diopter drum and a front post installed in a hooded ring. The rear sight is adjustable for both windage and elevation with the use of a special tool, being adjusted at the factory for firing at 25m with standard 124 grains FMJ 9×19mm NATO ammunition; the drum provides four different apertures of varying width used to adjust the light entrance in the diopter system, according to the user's eye relief and tactical situation. (Variants list) MP5A1: No buttstock (endplate/receiver cap in place of buttstock), "SEF" trigger group.[22] MP5A2: Fixed buttstock, "SEF" trigger group.[22] MP5SFA2: Fixed buttstock, single-fire (SE) trigger group.[22] MP5A3: Retractable buttstock,"SEF" trigger group.[22] MP5SFA3: Semi-automatic carbine version of MP5A3. Retractable buttstock and single-fire (SF) trigger group.[22] MP5A4: Fixed buttstock, 3-round burst trigger group.[22] MP5A5: Retractable buttstock, 3-round burst trigger group.[22] MP5-N: Model developed specifically for the U.S. Navy. Ambidextrous "Navy" trigger group, 3-lug/threaded barrel for attaching a sound suppressor; rubber-padded retractable stock. POF-4 PISTOL: Pakistan Ordnance Factory semi-auto copy of the MP5K.
