Dunkirk

I can’t believe we’re actually going to try this. The idea might have worked over a century ago, but that was during a time wence combat was contained to the detectable, to what the human eye could see with little assistance from things like radar and sonar.

Not in modern combat.

“Hold steady at final waypoint, Helm.”

“Aye captain,” the helmsman responds softly. “Coming up on final waypoint now.”

The rumble of the destroyers quad core thermoreactor falls to a hestiante vibration. Not many use the Delta class destroyer, fewer still faithfully command it from it’s unique ‘sunken’ bridge situated just forward of the engineering section, deep within the armored warship.

“Holding steady.”

“Thank you, Helm.” Facing the tacdisplay to the rear of the bridge, I study the dots, numbers and letters listing the displacements of warships, obstacles, defense arraries and the objectives.

“This ain’t gonna be easy,” my tactical officer mumbles.

“All ships, all ships, this is Fleet Admiral Yamamoto, commander of the Free Asian Navy Battleship Tokyo.” I stiffen at the sudden announcement. “All fleet elements gathered here are being merged into my command until such time as we accomplish our mission. Civilian  supply conveys have been trapped in this system by Deverish Assault fleets. Our job is to escort the volunteer rescue fleet as they deploy to secure any and all survivors amongst the debris and embattled.”

“He sure does like to run his mouth.”

I nod in agreement, saying, “It comes with the celebrity status. Helm!”

“Captain?”

“Plot a course in system, sent it to those assigned to our element and our charges. Three quarter impulse.”

I turn to the weapon’s station.

“Tactical, arm all silos and tubes.”

“Copy that, ma’am. Arm missile silos and torpedo tubes.”

“Course laid in…” the helm’s officer turns to comms. “Ready for transmission.”

I see my lead communications officer hold up her hand, slowly counting from four, fingers dropping with each number, and mouthing ‘done’ the moment her arm begins to drop.

And so it begins.

“All squardon elements, make intra-system jump.” I avidly stare down the mission chrono. “Now!”

Four zeroes slam red moments after I speak and I watch several other warships lurch forward along invisible paths leading into the danger zone. My brain rejects the idea, the lunacy that is high command’s decision to fly into a known, yet widely unexplored nebula.

“Fighter escort is ready for drop orders.”

My eyes drift to the little carrier symbol, a triangle with two rectangles off it’s longest side.

My eyes then drift to an enhanced view of our course whereupon I spot a nasty navigation obstacle for our larger vessels.

Asteroids.

While never truly close enough to stop a headstrong or foolhardy ship captain, these drifting debris from the formation of the solar system are large enough to cause navigation problems for the carriers as their slow maneuvering speeds never allow, the English have been turning asteroids around their territory into free floating mines, effectively squeezing invading warships into tightly packed formations.

“Tactical, fire a salvo of torpedoes into that field, wide spread.” A screen pops up to my right. “On my mark.”

I can see the paths each torpedo will take, the rotation of the asteroids, the speed of the element around my vessel.

There!

“Fire!”

“Torpedoes away.”

“Friendlies moving to avoid torps,” My communications officer speaks up. “Birds are leaving nest.”

I watch the swarm of smaller craft now clouding the carrier symbol, almost entirely obscuring its place on tactical display on the main screen.

The torpedoes will take time, maybe a little more than ten minutes.

“Helm, shut down the engines. Let us drift along our current heading. Comms, the other captains are to do the same.”

“Aye ser, transmitting now.”

“Engines going into standby.” the helmsman turns to face me. “We're drifting now, ma'am.”

A nod from me turns the helmsman back to their station, the bridge falling quiet as time drags on longer. There is always a chance something can go wrong, and those odds only grow as the operation grows more complex.

I sigh, pulling the operation file onto a display beside my right arm.

END TRANSMISSION]

It seems so easy.

Yet there are too many what ifs.

Letting a sigh escape from my lips, I glance over to my second in command.

“Are all vessels ready?”

I see the markers representing our torpedoes vanish from the main screen, taking several of the asteroids off the display too.

“Aye captain.”

“Comms, all captains are to resume; half speed, same heading.” A thought occurs to me. “Comms, go ship wide. Play Trevor Morris, Dragon Age accompaniment ‘The Inquisition Marches’, if you will.”

No one questions the unusual request. If anything, my communications officer nods in understanding as they broadcast the melody through the ship's PA system.

“All Elements, active scans are detecting enemy fleet movement around our three asteroids.”

I jerk a nod in the direction of my sensor officer, and see our own scanners go live, active springing up around three asteroids, each marked with a pulsing green.

Normandy.

Gallipoli.

Verdun.

“Tactical! Primary batteries to railgun configuration, secondary batteries to energy fire. Bring Anti Starfighter and Point Defense arrays online. Helm, bring us down ten degrees, assault velocity. Comms, spread the word to the rest of the Element; only engage when a critical is guaranteed and don't go off chasing the British.”

“Aye captain, communique is sent.”

“Cycling secondary batteries energy capacitors.”

“Primary weapons engaging recoil. Rounds materialising.”

“Dropping ten degrees relative to solar plane.”

“Starfighters are coming along our flanks. Thirty minutes out from maximum firing range.”

That's the trouble with combat nowadays.

If you can see you're enemy well enough to prepare, you can be damn sure that they too are ready.

“Fourth Element is engaging fringe units, twenty thousand kilometres out from target, sustaining non critical damage.”

“Second Element diverting course to assist. Estimated time, ten minutes.”

“XO, what is our time from the Second and Fourth Elements?”

“Twenty minutes, ma'am.”

Too long.

And I can't risk my command trying to support two other Elements in among these floating debris.

But still… something doesn't quite feel right.

“Comms, inform Captain Jericho to deploy his complement of Starbombers.” I turn the chair around to face forward, climbing out of it. “I want the starfighters covering them at all times. Tactical, I need you to pick out targets of opportunity for the bombers.”

“Aye captain.”

“Captain Jericho has confirmed the order.”

A group of ovals separate from carrier symbol, the bomber squadron’s representation steadily putting the carrier behind them. Lacing my fingers together, I press my form into the cushioned command chair and watch as the Elements new vanguard force separates and accelerates past the former asteroid mines.

“Commander Alexandra, situation report.”

“Admiral Yamato, Thirteenth Element is accelerating toward our objective.” A flick of my hand cues the helmsman in. “Resistance is negligible, will update as the situation unfolds.”

Dull flashes across the forward screen steal my gaze.

“Tactical, report!”

“Bombers clearing a path, ser. Zero contacts.”

Intently watching the screen ahead continues to update with information as sensor pings return from the vanguard ships. Even with this information I know there's more to be seen, enemy forces just out of range or hiding around the next asteroid.

“Time to objective?”

“Estimated time is forty minutes, ser.”

Wringing my fingers under my chin soothes some of the adrenaline throbbing into my blood, the knife twisting emotion twinging any time some chunk of solar debris sails past a destroyer or civilian pleasure craft.

The dull flash from the alarms doesn't help me in the slightest.

“Number Two, report.”

Wary of the significance behind the flashing and the asteroids floating around the formation, I swivel my chair around to face their station when no answer is forthcoming.

“Number Two!”

“E-enemy battlecruiser… it’s coming around the third asteroid from our portside escort, its anti ship defenses are tearing apart the vanguard.” His hands are gracing across the board before him. “Our path will run right through that battlecruiser if we don't do something.”

“Of course it will.”

The utterance was for my ears only however I know from the twitch on my Second’s left hand that he heard the bite in my voice, understood the lack of resonate criticism.

Weight begins to slip sideways as the forward view shifts away from the closing English starship, the forming path carrying the mass that is my own starship away from the hostile field of fire and a potential catastrophe.

Fuck that.

“Helm, bring us back on our previous heading, cut engines and bring us around to Port. Tactical, target that battlecruiser with the everything we have.” My feet root themselves to the decking. “We're going to clear a path for the civvies.”

“Aye cap’n,” the Helm officer signals. “Returning to previous heading.”

“Primary and Secondary weapon systems locking on target. Firing solutions coming in now.” A series of reticles paint across the forward view. “StSs are going hot.”

My cheeks crinkle with a smirk, my mind racing several steps ahead, ever adjusting and revising the plan forming in my mind, locking my arms in the small of my back to further reinforce the stance I hold before my crew.

There’s another shift, more subtle than the previous, and the artificial gravity drops into obscurity as the shift of the warship carries past the initial inertia. The familiar hum from the core drops as we begin to drift, with considerable velocity, ever closer to the enemy position with our starboard exposed to their fire.

“Kill shots only, Tactical,” I bark. “Run it down the line.”

“Aye captain.”

Fire lashes out from the English warship, scoring glancing blows across the bow and stern while scarring the starboard armor plating. Engineering begins calling out damage reports and initial assessments detailing the extent of the punishment we are taking.

Still, we must get closer.

The decking beneath my feet buckles and rushes to meet me, only for my head to glance off the steel and for me to begin floating toward the ceiling.

“Artificial gravity is suffering power shortages.” I watch the engineering officer glance around. “Captain?”

“Eyes on your stations crew!” I bark, trying to orient myself, my feet aimed deck ward. “Gunners, open fire!”

Strobes of light lance forward from the forward main batteries, hyper velocity shells within the globs of light being flung forward, brighten the forward view screen moments before it dims to black.

“Tactical display on the main.” I shunt off the ceiling and float toward the center. “Call out the hits.”

“All shots absorbed before detention occurred.”

“Concentrate fire on their propulsion section.” I let a moment pass. “Open fire!”

Shudders through the decking are the only warning we get that the warship’s armaments have fired again, flinging more material toward the closing enemy ship. Tactical calls out again, reporting a single strike across the port engine housing of the battlecruiser, a glancing blow if anything else.

But I'll take what we can score.

“Primary arraries, switch to shock mode.”

Lights around the bridge dim substantially, a slight flicker to console screens the only warning that the gunnery crews heeded my instruction and have resumed firing upon the battlecruiser. Those on the bridge immediately around me scurry to adjust their stations to avoid losing control of the destroyer to a power overload.

The shock mode for the four primary weapon arraries draws more energy from the thermoreactors to supercharge the magnetic rails, propelling shells at, up to, triple the standard firing velocity, with the drawbacks including a slower firing rate and lower heat efficiency.

“Port side arraries have a lead.”

“Open fire!”

Reverberations shudder through the decks despite the recoil springs keeping the twin rails of each array from tearing free from their housings. Six lances of light slash out, two thirds slamming into asteroids or wrecks, the remaining two grazing the upper and lower bridge shields respectively. I duck reflectively as the British returning fire slams into the forward cannons, shields flaring bright under the burden.

“Portside Array Three is disabled, all crew lost.”

Yet, there hadn’t been any warning signals, nothing foreshadowing the failure of the shields.

This can’t have happened…

“Analysis, science?”

“Data is inconclusive, however scans are yet to be completed,” comes the swift reply from my science officer. “Our shields are still operational, refreshing rate is nominal.”

“Unlock the ventral and dorsal batteries,” Tactical is barking, his words ringing in my ears. “All arraries are to switch to solid projectiles.”

H-how… could they have…

“Ventral battery a’justing for spin.”

Nothing is able to penetrate Inquisition shields...

“Dorsal battery has a lock and is about to lead.”

N-nothing…

“Batteries are fully charged an’ ready ta fire. Target's a’justing its course.”

“Captain?”

I glance up from the arm display and do my best to swallow the globe lodging itself in my throat. My Tactical officer is waiting beside his station, hand blocking his mic, eyes intently urging. I let my gaze drift across the bridge, noting that everyone holds the same uriging intent in their eyes.

I suppose it really doesn't matter how it happened, it just did and we must insure that another hit like that or worse befalls us or the civilian craft within our Element.

“Scopes are picking up multiple hostiles coming around from the dark side of the target asteroid,” Tactical calls out. “Science, what are you ge’ing?”

“Energy readings are spiking across the board.” The science officer falls silent.

Light snaps out from the English battleship, our own railguns strobing with energy as we exchange fire while the destroyer drifts ever closer to the larger vessel. Crew occasionally stagger around me when the English score a hit against us, often stumbling over unless someone else intervenes before their heads connect with anything solid.

Damage reports continue to cycle through to the bridge; the starboard hangar is sealed shut by a glancing blow, compartments along the upper portside decks have either been breached or are damaged beyond operational use, the portside battery has been confirmed to be inaccessible from within the ship without risking the rest of the crew and our shield refreshers are beginning to toe their red lines.

I'm about to demand a response from my science officer when we're struck squarely by the enemy warship, alarms screeching and lights flickering as power from the core falters for the briefest of moments.

“Somebody report!”

Science groans when the adjust them self at their station.

“Energy readings from that hit match whatever knocked out portside Array Three, definitely not one of ours and the energy sensors picked up something off the charts moments before impact. The computer is triangulating from what data our sensors have picked up.”

“Navigation, begin plotting for a Rift jump, I want possible trajectories that will carry us pass that battleship without leaving us vulnerable to return fire. Helm, keep us moving, I don't want to take anymore hits like that last one unless we're covering the civilians, understood?”

“Aye cap’n. Increasing to Attack speed, down angle dropping to three point seven seven nine degrees. Engaging operational maneuvering thrusters.”

“All weapons arraries are adjusting for course correction,” Tactical sounds off. “Torpedo launches detected, tracking them now.”

“Triangulation complete! Right in the middle of the fleet crossing the asteroid's equator.” The science officer, now they've got my attention, gestures toward the midsize screen beside them. “There it is.”

I stare at the peculiar construct the sensors are being aimed at, noting the large barrel like centerpiece protruding from within what appeared to be a loose ball of large, rotating panels. What the sensors could see of the engines gives the idea that they are either embedded into the “sphere” of panels or loosely attached behind the rest of the construct.

“A glass cannon? Sir, if the English fleet have deployed one to this system, the rest of the fleet may not be able to survive a retreat from the system.” The Tactical officer comes into view, tapping on the screen. “And if they have one here, there's no way of telling how many more could possibly be here.”

I nod my head, eyes tracing the Elements path to the asteroid. To get the civilian ships surface side there can't be anything left to chance and that requires clearing out any entrenched defenses nearby.

“Nav, are those coordinates locked in?” A nod from the officer puts a grim smile on my face. “All hands, all hands, abandon ship. I repeat, all hands, aban-”

“We're not going anywhere.” My XO salutes firmly.

Sending a glare at the officer, I collapse back onto the command chair, gaze returning to the main viewport and the stars, asteroids and debris ahead. Beyond that, I can not see what the ship can see, can not determine who will survive if we Rift into the center of the enemy formation.

Because I can't protect them all.

Yet they're choosing to stay.

Pulling a ragged breath into my lungs, I give him a nod.

“Alright, to your stations. Nav, start counting down; Helm, begin corkscrewing the ship, portside; Tactical, coordinate with Weapons and the weapon crews to begin inflicting maximum damage as soon we exit Riftspace.”

The XO turns to me.

“On your order, cap’n.”

“Jump!”

The destroyer begins to roll over, spinning around its central axis in an ever increasing twirl toward the Rift tearing into the fabric of space and time just ahead.

“Operational weapons are reporting readiness, sir!” Tactical reports. “Missile pods are armed, and we have torpedoes in all eight forward tubes.”

“Crossing through the Rift in t-minus twenty.”

“All hands brace for Rift!” I bark into the intercom, fingers tightening around the bar above my head.

“Crossing in ten…”

The Rift tears wider apart, edges crackling with dimensional energy.

“Nine…”

It's spinning now, like a cosmic whirlpool.

“Eight…”

Debris is beginning to fall in.

“Seven…”

Collisions are increasing as the vortex snares increasingly more debris within it's jaws, the event horizon pulsing as smaller chunks fall through into Riftspace to be amongst the celestial debris already dancing on the other side.

“Six…”

Time begins to warp around me, light waves dancing into sight around the bridge crew.

“Five…”

A jolt runs into my legs when the destroyer begins grazing the event horizon.

“Four…”

Flares of light appear across the view screen.

“Three…”

Debris is splintering and cascading across the starship's shields.

They'll hold.

“Two…”

Details are coming through the rift aperture, floating platform like rocks and asteroids that make up the extra dimensional plane, a labyrinth not meant for mortals to venture through.

“One… Rifting!”

Japan Commissions 10th Soryu-Class Diesel-Electric Attack Submarine

The Japan Maritime Self Protection Force’s most recent diesel-electrical assault submarine was commissioned on March 18.

The Japan Maritime Self-Protection Power (JMSDF) commissioned its tenth Soryu-class diesel-electric powered assault submarine (SSK), the JS Shuriyu, through an formal ceremony that took position at the Kawasaki Heavy Industries (KHI) shipyard in Kobe in Hyogo Prefecture on March 18, KHI explained in a assertion. The new SSK was officially inducted into the JMSDF’s Submarine Flotilla 1, centered in Kure, Hiroshima prefecture.

The commissioning ceremony was attended by senior Ministry of Defense officials, substantial-ranking JMSDF officers, and protection market representatives. The Shuriyu was laid down in January 2015 and launched in November 2017. It is the fifth Soryu-class attack sub to be designed by KHI and the 28th boat in general produced by the shipbuilder given that the close of Planet War II. Total construction costs of the new submarine are approximated at 53-56 billion yen ($496-502 million).

The JMSDF programs to commission two additional submarines of the course in 2020 and 2021 respectively, which will carry the whole range of Soryu-course SSKs to 12. Notably, the first Soryu-course SSK fitted with lithium-ion batteries, the potential JS Oryu, was launched in Oct 2018. The ninth Soryu-class SSK, the JS Seiryu, was commissioned in March 2018. The Seiryu was designed by Mitsubishi Major Industries (MHI). It is the fifth Soryu-class and the 27th SSK built overall by MHI since 1945.

As I explained previously:

The 4,200-ton (submerged) Soryu-course boats are the JMSDF’s very first SSKs to be fitted with air-unbiased propulsion (AIP) units, enabling the submarines to keep underwater for up to two weeks. (…) In 2015, Japan’s Ministry of Defense (MoD) introduced that it intends to equip the last two boats of the class with lithium-ion batteries. (According to some studies, the other boats of the course will be retrofitted with the batteries as perfectly.)

Soryu-class SSKs are powered by two Kawasaki 12V 25/25 SB-variety diesel engines and four Kawasaki Kockums V4-275R Stirling AIP engines for silent managing. The boats have an estimated range of 6,100 nautical miles (11,297 kilometers) with a utmost floor speed of 13 knots and a subsurface travelling velocity of 20 knots. The highest diving depth of the sub is close to 650 meters.

The Soryu-class is equipped with six HU-606 533 mm torpedo tubes that can accommodate Kind 89 heavyweight homing torpedoes and UGM-84 Harpoon anti-ship missiles. Upcoming to bow-and-flank-mounted Hughes/Oki ZQQ-7 sonar arrays, the sub is also geared up with a towed array sonar capable of detecting ships more than 70 kilometers away.

Additionally, I noted:

The Soryu-class boats’ hydrodynamic design is based on the older Oyashio-class diesel-electric assault submarines at this time in assistance with the JMSDF. It is (…)  equipped with a laptop or computer-managed, Swedish-designed X rudder to improve the submarine’s maneuverability when working in shallow waters close to the seabed.

It is also noteworthy that crew aboard a Soryu-class SSK is more compact than on previous JMSDF subs and usually is composed of nine officers and 56 sailors.

Indonesian Navy receives pitch for Type 214 submarine from Golcük Shipyard

Key Points

Indonesia has added the Type 214 class to a list of submarine platforms it is now considering

Talks are in line with the Indonesian Navy's strategy of diversifying the mix of its future submarine fleet

The Indonesian Navy (Tentara Nasional Indonesia - Angkatan Laut, or TNI-AL) has received an offer from Golcük Shipyard to supply a variant of the Reis (Type 214)-class diesel-electric submarine (SSK).

Multiple TNI-AL sources have confirmed with Jane's that meetings and presentations on the Type 214 class were conducted from early 2017 by a team of Golcük Shipyard and TKMS officials at the TNI-AL headquarters in Cilangkap near Jakarta.

The meetings will be followed by a visit of TNI-AL officials to Golcük Shipyard's facilities near Istanbul, where they will observe construction work on the Turkish Navy's first Type 214 boat, Pirireis (S 330). This visit is currently scheduled to take place from 7 to 12 May 2017, in parallel to the IDEF 2017 exhibition.

The Turkish Navy is anticipating the delivery of six Type 214 submarines from Golcük Shipyard. The first of-class is slated for launch in 2019, and all six boats are expected to be commissioned by 2025.

According to Jane's Fighting Ships , the Reis-class SSK features an overall length of 67.6 m, an overall beam of 6.3 m, and a hull draught of 6.0 m. The platform, which can accommodate a crew of 27 including five officers, has a top speed of 20 kt when dived, and 12 kt when surfaced.

The boat is equipped with bow, flank and towed array sonars, and eight tubes that can launch 533 mm torpedoes including the Raytheon Mk 48 Mod 6, and the Atlas Elektronik DM2A4.

Japan to Commission 10th Soryu-Class Attack Sub This Month

The Japan Maritime Self-Defense Force’s most up-to-date diesel-electric powered assault submarine will be commissioned on March 18.

The Japan Maritime Self-Protection Force (JMSDF) will fee its tenth Soryu-class diesel-electrical assault submarine (SSK) for the duration of an official ceremony to be held at the Kawasaki Significant Industries (KHI) shipyard in Kobe in Hyogo Prefecture on March 18, the provider announced in a assertion.

The new SSK, the long run JS Shuriyu, was laid down in January 2015 and launched in November 2017. It is the fifth Soryu-course SSK constructed by KHI and the 28th boat general manufactured by the shipbuilder given that 1945. Two additional SSKs are anticipated to be commissioned in 2020 and 2021 respectively, which will bring the overall number of Soryu-course boats to 12.

The ninth Soryu-class SSK, the JS Seiryu, was commissioned in March 2018. The boat was built by Mitsubishi Hefty Industries (MHI) and is the fifth Soryu-class and the 27th SSK built over-all by MHI since the stop of Entire world War II. The future Shuriyu and the Seiryu every cost all over 53 billion yen ($496 million) to constructed.

The Soryu class is considered to be one particular of the most highly developed SSKs currently in services with any Navy in the world. As I explained previously:

The 4,200-ton (submerged) Soryu-course boats are the JMSDF’s initial SSKs to be fitted with air-impartial propulsion (AIP) programs, enabling the submarines to stay underwater for up to two months. (…) In 2015, Japan’s Ministry of Defense (MoD) announced that it intends to equip the final two boats of the class with lithium-ion batteries. (In accordance to some experiences, the other boats of the course will be retrofitted with the batteries as effectively.)

Soryu-course SSKs are driven by two Kawasaki 12V 25/25 SB-kind diesel engines and 4 Kawasaki Kockums V4-275R Stirling AIP engines for silent jogging. The boats have an approximated selection of 6,100 nautical miles (11,297 kilometers) with a maximum surface area speed of 13 knots and a subsurface travelling pace of 20 knots. The optimum diving depth of the sub is about 650 meters.

The Soryu-class is fitted with 6 HU-606 533 mm torpedo tubes that can accommodate Type 89 heavyweight homing torpedoes and UGM-84 Harpoon anti-ship missiles. Subsequent to bow-and-flank-mounted Hughes/Oki ZQQ-7 sonar arrays, the sub is also geared up with a towed array sonar capable of detecting ships around 70 kilometers away.

As a end result of the Soryu-class SSKs’ substantial diploma of automation, the boat’s crew is more compact than on earlier JMSDF subs and consists of 9 officers and 56 sailors.

Furthermore, I noted:

The Soryu-class boats’ hydrodynamic design is dependent on the older Oyashio-class diesel-electric powered assault submarines at the moment in company with the JMSDF. It is (…)  equipped with a laptop-managed, Swedish-developed X rudder to increase the submarine’s maneuverability when running in shallow waters close to the seabed.

Notably, the 1st Soryu-course SSK fitted with lithium-ion batteries, the long term JS Oryu, was introduced in Oct 2018.

The class is also known under the name Bars (meaning "snow leopard"). There are four sub-classes or flights of Shchuka, consisting of the original seven Akula Is, commissioned between 1984 and 1990; six Improved Akulas, commissioned between 1991 and 2009; one Akula II, commissioned in 1995; and one Akula III, commissioned in 2001.[citation needed] The Russians call all of the submarines Shchuka-B, regardless of modifications. Some potential for confusion may exist, as the name Akula (Акула meaning "shark" in Russian) was used by the Soviets for a different submarine, the Projekt 941 which is known in the West as the Typhoon class. By contrast, the Projekt 971 (the subject of this article) was named Shchuka-B by the Soviets but designated as the "Akula class" by the West after the name of the lead ship, K-284. The launch of the first submarine in 1985, according to defense analyst Norman Polmar, "shook everyone [in the West] up", as Western intelligence agencies had not expected the Soviet Union to produce such a boat for another ten years.

In the USSR, they were produced as Project 671 (Russian: Проект 671). Victor-class subs featured a teardrop shape, which allowed them to travel at high speed. These vessels were primarily designed to protect Soviet surface fleets and to attack American ballistic missile submarines. Project 671 begun in 1959 and design task was assigned to SKB-143, one of the two predecessors (the other being OKB-16) of the famous Malachite Central Design Bureau, which would eventually become one of the three Soviet/Russian submarine design centers, along with Rubin Design Bureau and Lazurit Central Design Bureau.
