The SLS (Space Launch System) Core Stage by Numbers

Technicians with NASA and SLS core stage lead contractor Boeing, along with RS-25 engines lead contractor Aerojet Rocketdyne, an L3Harris Technologies company, are nearing a major milestone for the Artemis II mission. The SLS (Space Launch System) rocket’s core stage for Artemis II is fully assembled and will soon be shipped via barge from NASA’s Michoud Assembly Facility in New Orleans to the agency’s Kennedy Space Center in Florida. Once there, it will be prepped for stacking and launch activities.

Get to know the core stage – by the numbers.

Standing 212 feet tall and measuring 27.6 feet in diameter, the SLS core stage is the largest rocket stage NASA has ever built. Due to its size, the hardware must be shipped aboard NASA’s Pegasus barge.

900 miles

Once loaded, the barge – which was updated to accommodate the giant core stage -- will travel 900 miles to Florida across inland and ocean waterways. Once at Kennedy, teams with our Exploration Ground Systems team will complete checkouts for the core stage prior to stacking preparations.

18 Miles + 500 Sensors

As impressive as the core stage is on the outside, it’s also incredible on the inside. The “brains” of the rocket consist of three flight computers and special avionics systems that tell the rocket what to do. This is linked to 18 miles of cabling and more than 500 sensors and systems to help feed fuel and steer the four RS-25 engines.

8.8 million

Speaking of engines… Our SLS Moon rocket generates approximately 8.8 million pounds of thrust at launch. Two million pounds come from the four powerful RS-25 engines at the base of the core stage, while each of the two solid rocket boosters produces a maximum thrust of 3.6 million pounds. Together, the engines and boosters will help launch a crew of four Artemis astronauts inside NASA’s Orion spacecraft beyond Earth orbit to venture around the Moon.

733,000 Gallons

Achieving the powerful thrust required at launch calls for a large amount of fuel - 733,000 gallons, to be precise. The stage has two huge propellant tanks that hold the super-cooled liquid hydrogen and liquid oxygen that make the rocket “go.” A new liquid hydrogen storage sphere has recently been built at Kennedy, which can store 1.25 million gallons of liquid hydrogen.

Four

The number four doesn’t just apply to the RS-25 engines. It’s also the number of astronauts who will fly inside our Orion spacecraft atop our SLS rocket for the first crewed Artemis mission. When NASA astronauts Reid Wiseman, Christina Koch, and Victor Glover along with CSA astronaut Jeremy Hansen launch, they will be the first astronauts returning to the Moon in more than 50 years.

Defense contractor L3Harris to procure Aerojet Rocketdyne for $4.7B

L3Harris Technologies Inc. announced an agreement to acquire Aerojet Rocketdyne Holdings Inc. in a $4.7 billion transaction that would cement L3Harris' position as one of the Pentagon's six primary defense contractors.

Aerojet is a major manufacturer of missile engines, including the Javelin used by Ukraine. Its product also helps power NASA rockets and US military hypersonic systems designed to counter China's military expansion.

Aerojet was relisted for sale after federal regulators filed suit in January 2022 to block Lockheed Martin Corporation's planned $4.4 billion acquisition of the company on antitrust grounds, sparking a bitter internal board battle.

According to individuals involved in the negotiations, L3Harris' all-cash offer of $58 per share trumped competing bids from General Electric Co. and Textron Inc. A transaction is anticipated to face intense regulatory scrutiny at a time when Aerojet is also experiencing production difficulties. Continue reading...

The U.S. defense industrial base just got a $20 billion shot in the arm from the national security supplemental bills passed by Congress last week. But although officials and experts believe the funding will provide a much-needed jolt to military production and help open up new factory lines, some say it’s still not enough to respond to China, Russia, and terror threats at the same time.

“We have begun—begun—to rebuild the industrial base with the supplementals,” Bill LaPlante, the Pentagon’s acquisition chief, said at an event last week. “Calling it a wartime footing, no.”

The biggest need? Money. Officials and experts say that the United States needs more of it, lots more, to make the real investments. At the peak of World War II, the United States was spending nearly 40 percent of its GDP on defense. It’s down to less than a tenth of those spending levels now. And the need to spend more has gone up with the Chinese spending more—and with Russian factories working around the clock.

“It’s still shy by quite a bit [for] what you would need to get our stockpiles in the right shape, get our industrial base in the right shape, help the Taiwanese, and get the Ukrainians in a position that they can get some leverage in negotiations,” said Jeb Nadaner, a former U.S. deputy assistant secretary of defense for industrial policy. “If the benchmark is against the calendar and the clock, we’re still falling behind every month. And that can’t go unnoticed by China.”

But the jolt will allow the United States to surge artillery production and solve key bottlenecks.

One is the production of solid rocket motors used for everything from Javelin anti-tank weapons that can hit a tank from a little over a mile away to intercontinental ballistic missiles that can propel warheads across the Atlantic and Pacific oceans if a U.S. war with Russia or China ever went nuclear.

Aerojet Rocketdyne, which was recently bought out by L3Harris Technologies for nearly $5 billion, was one of only a few suppliers. But the supplemental gives several billions of dollars for companies, such as Orbital ATK, to expand their solid rocket motor facilities.

And it provides money from the Defense Production Act—the same law that Washington used to force U.S. manufacturers to produce more masks, gloves, and face shields during the coronavirus pandemic—to build out a second tier of rocket motor suppliers, including X-Bow Systems in Texas; Ursa Major in Colorado; and Adranos in Mississippi, which was recently bought out by defense technology company Anduril. The idea is to fast-track work that wasn’t going to be done until at least 2026, if not 2027 or 2028, according to a congressional aide, who spoke on condition of anonymity to talk about military contracts that hadn’t been made public.

There’s also about $100 million to help Williams, one of the only American makers of cruise missile motors, speed up production in Michigan. Those motors are used in the long-range anti-ship missile that might one day help Taiwan fend off Chinese landings; the armor-piercing joint air-to-surface standoff missile; the Tomahawk land attack missile that is the U.S. Navy’s weapon of choice; and the Harpoon missile that the Ukrainians have used in the Black Sea.

There’s also money to build factories for ball bearings, printed circuit boards, and other subcomponents for the $311 billion that the Pentagon wants to spend in the upcoming year to develop new weapons. Processor assemblies, castings, forgings, microelectronics, and seekers for munitions have been major bottlenecks. And there are recruitment and attrition problems almost across the board, from welders at shipyards to rocket engineers, a generational problem that might need vocational-training fixes at the high school level and up.

But with some Democrats pushing back on the Biden administration’s $850 billion Pentagon budget proposal as too costly, there’s also a focus on smaller attritable capabilities that don’t need a whole lot of start-up capital or defense industrial muscle to get moving.

There’s a ton of counter-drone money, about $600 million, that will go toward Coyotes, a small drone capable of intercepting other drones, and Roadrunners, an air defense munition that takes off vertically—just like the F-35 fighter jet variant flown by the U.S. Marines.

Some members, such as House Armed Services Committee ranking member Adam Smith, have advocated for ending production of ground-launched nuclear weapons. Congress is also trying to scrap old weapons, including F-15 fighter jets, the A-10 Warthog aircraft, and littoral combat ships used by the Marines. Smith is even curious about using microwaves as the next generation of air defense instead of directed energy.

The United States is also torn between near-term needs, like 155 mm artillery ammunition, and long-term needs—like a sixth-generation fighter jet that will follow the F-35. “There are going to have to be some trade-offs between preparing for a near-term fight and near-term deterrence and probably making some trade-offs on some next-generation weapons systems,” said Seth Jones, the senior vice president and director of the international security program at the Center for Strategic and International Studies in Washington, D.C.

Russia’s invasion of Ukraine is still going to be a major factor in setting requirements for the U.S. military. “We’re going to be selling 155 [mm] like a drunken sailor for a few years,” said Mark Montgomery, a senior fellow at the Foundation for Defense of Democracies. “The Western alliance needs the U.S. to crank 155 [mm] for a decade.”

Other weapons used in the early days of Ukraine’s defense of Kyiv are likely to hit a plateau in production. Those include Javelin systems; the High Mobility Artillery Rocket System, or HIMARS; and Stinger anti-aircraft missiles, which the Pentagon sent to Ukraine in large numbers early in the war and are also included in the supplemental, but which have taken on a secondary role as the fight has been bogged down in trench warfare for months and months.

Allies can help solve some of the bottleneck problems. The United States is co-developing new glide-phase interceptors with Japan as well as co-producing guided multiple-launch rockets with Australia and guidance-enhanced missiles for Patriot air defenses with the Germans. But after the political fights that took the supplemental more than six months to get through Congress, LaPlante and other officials acknowledged that the United States now has an image problem in showing itself to be a reliable torch-bearer for the global defense industrial base.

There’s another major production plateau that members of Congress are trying to stave off: attack submarines. The Biden administration’s proposed budget for the upcoming year slashed funding for one attack submarine. For years, producing two a year had been the standard, even though U.S. shipyards only produce between 1.2 and 1.4 Virginia-class submarines each year, and new variants are 24 to 36 months behind schedule.

And there are dependencies that are difficult—if not impossible—to cut. The United States still buys a significant amount of its titanium from Russia, which is used for everything from landing gears to tank armor, and is only slowly ramping up production of rare earth minerals, which are dominated by China. But the U.S. military’s weapons are ravenous for rare earths: The F-35 needs 900 pounds of rare earths to run, and the Virginia-class submarines need more than 10 times that amount. The military also needs lithium ions used in advanced battery production that China also dominates.

Where Congress and the Pentagon are having more trouble jolting the defense industrial base to life is for weapons that might be used in the Indo-Pacific. The U.S. Army’s precision strike missile that would be used to hit incoming Chinese ships from more than 600 miles out, for instance, is still being developed—the seeker that would find enemy vessels isn’t finished—so there’s no way to ramp up capacity, at least not yet.

But before the United States ramps up industrial capacity, some members of Congress want the Pentagon to take a good, hard look at what’s already on the books.

“Where can we look within the budget and say, wouldn’t we be better to spend more money on these things that we really do need?” Smith said. “So before I get into a discussion about, ‘Gosh, it’d be great if we had another $50 billion,’ where are we spending the money that we have? I think that’s the first question.”

Gateway's propulsion system testing throttles up

The powerhouse of Gateway, NASA's orbiting outpost around the moon and a critical piece of infrastructure for Artemis, is in the midst of several electric propulsion system tests.

The Power and Propulsion Element (PPE), being manufactured by Maxar Technologies, provides Gateway with power, high-rate communications, and propulsion for maneuvers around the moon and to transit between different orbits.

The PPE will be combined with the Habitation and Logistic Outpost (HALO) before the integrated spacecraft's launch, targeted for late 2024 aboard a SpaceX Falcon Heavy. Together, these elements will serve as the hub for early Gateway crewed operations and various science and technology demonstrations as the full Gateway station is assembled around it in the coming years.

In this image, PPE engineers successfully tested the integration of Aerojet Rocketdyne's thruster with Maxar's power procession unit and Xenon Flow Controller.
