Three Additive Rocket Motor Awards in a Week, With No Quantities Disclosed
Printed rocket propellant now has a named Army cruise missile to feed. It still has no disclosed motor order. At the AUSA annual meeting in Washington, X-Bow Systems said Leidos had selected it to develop and produce the booster motors for the Army's Low-Cost Containerized Munition, or LCCM (Company PR, Oct. 12, 2026). Five days earlier, X-Bow announced a Navy booster award worth nearly $70M. Shortly before that, Ursa Major won Navy awards to qualify its additive Lynx motor line. We argued in our Ursa Major analysis that those awards bought qualification time rather than volume.
Read together, the three announcements describe one way of buying. The Pentagon and its primes are reserving qualification slots for new additive propulsion suppliers on munitions meant to be bought in large numbers. They are paying for design, tooling and test, and holding back on quantities. That is a sensible way to buy from unproven suppliers. It also means the award count says little about whether printed propellant will ever ship at rate.
The Leidos selection matters because it attaches a public date to that question.
What Leidos Actually Bought From X-Bow for the LCCM Booster
The booster is the stage that pushes the LCCM cruise missile out of its launch container and brings it up to flying speed. Under the agreement, X-Bow will move through design, qualification testing and static fires before full-rate production of booster motors at scale in 2027 (Company PR, Oct. 12, 2026). Defense Daily's Cal Biesecker reported the same 2027 full-rate expectation, sourced to X-Bow (Defense Daily, Oct. 12, 2026). Neither company disclosed a contract value or a motor quantity.
The order of those steps matters more than the headline, because the booster can fail at each one. A selection that starts at design is a development assignment with a production option attached.
X-Bow's volume also depends on Leidos rather than directly on the Army. Leidos competes for LCCM business alongside Anduril, CoAspire and Kongsberg's Zone 5 Technologies. The same split shapes the low-cost cruise missile market we covered in our CoAspire piece. If Leidos loses share, a booster slot on its missile becomes a slot on a small program.
X-Bow calls this the latest of six new propulsion program selections it has won in 2026, spanning the Navy, Army and Missile Defense Agency (Company PR). That is a full pipeline. So far, none of it has turned into a signed production quantity.
The Navy's Nearly $70M Booster Award Tools the Same Luling Line
The Navy award from October 7 provides money the LCCM work will lean on. X-Bow said it won nearly $70M to develop a booster for future Navy missiles (Company PR, Oct. 7, 2026). According to the company, that money funds rate tooling at its Luling, Texas campus, where it processes propellant and runs static fires. Two program ramps now sit on one site, and Navy money is paying for equipment the Army booster will also need.
Luling was built ahead of any named missile program. X-Bow declared the facility ready for production in November 2025, before an Army or Navy booster existed to fill it. By late May 2026, it reported end-to-end energetic operations on two systems at the Texas site under the Air Force Research Laboratory's RE-ARM program: a containerized “Rocket Factory in a Box” and an industrial-scale Gen-0 line (Company PR, May 27, 2026). Founder and CEO Jason Hundley described the company's production vision as “a few million pounds of solid propellant per year.”
X-Bow's largest disclosed delivery so far came from its first major production contract. That contract, by the company's account, delivered more than 2,100 combat-ready rocket motors: rocket-assisted takeoff motors for AEVEX's Disruptor drone. A drone-launch assist motor is not a cruise-missile booster, and it never had to pass missile-grade qualification.
Anduril's McHenry Plant Sets the Throughput Bar for Printed Propellant
The fair benchmark is another new entrant, not the legacy suppliers. Anduril Rocket Motor Systems, built on Anduril's acquisition of Adranos, opened a full-rate solid rocket motor plant in McHenry, Mississippi. The company announced the opening on 5 August 2025, 18 months after breaking ground. Citing an Anduril blog post, Janes reported that the complex test-fired more than 700 motors in that period and that the new site is expected to reach around 6,000 tactical motors a year by the end of 2026 (Janes, Aug. 5, 2025). Anduril makes its propellant conventionally, and it holds its own LCCM frame.
X-Bow's process has to beat that. Anduril has shown that a newcomer can reach rate quickly with conventional processing and federal capacity support. X-Bow argues that its propellant process is more precise and flexible than traditional methods. No independent data has yet tested that claim at missile-booster scale.
The additive part of X-Bow's story is also narrower than the label suggests. Ursa Major prints motor cases and hardware, while X-Bow's additive claim lies in propellant processing. Even X-Bow's own terms vary: its May release spells AMSP as “Advanced Manufacturing of Solid Propellant,” while its company boilerplate calls the process additive. Our patent linkage currently associates 0 active patent records with X-Bow Systems. The linkage is name-matched and review-gated, so it undercounts, but it means we cannot yet independently confirm the “patented” label.
LCCM Static Fires and the 2027 Rate Date at Luling
Three dated checkpoints matter more than the next award announcement.
The first is the LCCM booster static fires. X-Bow has put qualification and static fires ahead of the 2027 rate date, so any slip will show up there first. The second is whether full-rate production actually starts at Luling in 2027, and at what quantity. The first disclosed motor count will reveal more than this selection did. The third is whether Luling can run two ramps at once. The Navy booster and the LCCM booster share one site, and the Navy program is the longer-dated of the two, so the Army booster is the nearer real test of rate.
Leidos's share of LCCM matters too. If the Army spreads early lots across the framework holders, X-Bow's 2027 volume could be modest however much Luling can produce.
Our own data shows how new this supplier is to the additive conversation. Our news pipeline logged 1 item matched to X-Bow Systems in the last 180 days, against 0 in the 180 days before. That count matches on company name only. The AM Pulse company index lists X-Bow as a growth-stage hardware company based in Albuquerque and founded in 2016, though index fields are unevenly populated across companies. The next X-Bow item worth logging is a static-fire date.
