Simplify's Take

What believers are saying

  • July 29, 2026 results showed $42 billion backlog and raised full-year guidance.
  • July 27, 2026 DoW agreements quadruple THAAD and triple PAC-3 propulsion output.
  • The July 13, 2026 satellite award expands immediate production across Indiana and Florida.

What critics are saying

  • Golden Dome and interceptor orders concentrate revenue on one conflict-driven Pentagon priority.
  • Aerojet's new capacity must execute by 2028, or deliveries miss DoW expectations.
  • BAE's April 2026 settlement shows recurring contract-dispute exposure around proprietary defense work.
  • Any PAC-3 or THAAD propulsion slip would damage U.S. deterrence trust and re-compete awards.

What makes L3Harris Technologies unique

  • Aerojet Rocketdyne powers PAC-3 MSE and THAAD propulsion, critical to U.S. missile defense.
  • L3Harris won July 13, 2026 AMDT3 satellites, linking space sensing to Golden Dome.
  • Vampire and Aeromet give L3Harris low-cost counter-drone and airborne test-verification niches.

L3Harris completes hot-fire test of stage two rocket motor for Next Generation Interceptor program

L3Harris Technologies has successfully completed a hot-fire test of its stage two advanced large solid rocket motor for the Missile Defense Agency's Next Generation Interceptor programme. The company conducted the test as part of the Lockheed Martin team developing the homeland missile defense system. The test validated the system's design integrity, with the motor completing a full-duration burn in a simulated high-altitude, vacuum environment. Engineers evaluated performance in conditions mimicking Earth's upper atmosphere. L3Harris serves as the primary propulsion and control systems provider for NGI, producing both stage one and stage two rocket motors, plus the Attitude Control System and Divert and Attitude Control System. The company manufactures components across facilities in California, Virginia, Alabama, and Arkansas.

Iran tensions expose defense supply gaps as AeroVironment lands $186M drone deal

Iran's recent attacks in the Strait of Hormuz and Red Sea have exposed critical shortages in defense supplies, particularly drones, precision weapons, and artillery shells. This situation presents opportunities for defense contractors positioned to scale production. AeroVironment secured a $186 million US Army order in February 2026 for Switchblade loitering munitions, part of a five-year contract with a $990 million ceiling. The systems enable small units to destroy armored vehicles without larger missiles. L3Harris Technologies reported orders of $7.8 billion in Q1 2026, with a book-to-bill ratio of 1.4 and record backlog of $40.7 billion. By Q2, backlog reached $42 billion on $7.3 billion in new orders, with revenue increasing 8% to $5.9 billion. Both companies are positioned to benefit from increased demand driven by ongoing conflicts.

US Pentagon signs seven-year deals with L3Harris and Lockheed Martin to expand missile defense production

The US Defense Department announced two seven-year agreements with L3Harris Technologies and Lockheed Martin on 27 July to expand propulsion capacity for Patriot and THAAD interceptors, addressing missile defence system shortages driven by Iran tensions. RTX also benefits as a key contractor and supplier for these systems. L3Harris is up 3% this year, whilst RTX and Lockheed Martin have gained more than 17% and 19% respectively. Lockheed reported Q2 revenue of $20.1 billion, up 11% year over year, with a record backlog of $230 billion. Through its Aerojet Rocketdyne business, L3Harris supplies solid-rocket motors for THAAD and Patriot missiles, benefiting from demand regardless of contract awards.

L3Harris to quadruple THAAD missile propulsion production under 7-year DoW contract

L3Harris Technologies has signed a framework agreement with the Department of War and Lockheed Martin to quadruple propulsion production for the Terminal High Altitude Area Defense (THAAD) system. The seven-year contract will be the largest THAAD propulsion award L3Harris has received to date and is expected to be finalised later this year. L3Harris produces THAAD's Solid Rocket Boost Motors and Liquid Divert and Attitude Control Systems for the Missile Defense Agency. The company manufactures these components at facilities in Huntsville, Alabama, Camden, Arkansas, and Los Angeles. The expansion builds on L3Harris' ongoing investments, which include constructing approximately 60 facilities and adding or upgrading nearly one million square feet of manufacturing and office space across its rocket motor production sites in Alabama, Virginia, and Arkansas.
