L3Harris taps Intuitive Machines to build 18 spacecraft for $1.8B missile defence mission

L3Harris Technologies selected Intuitive Machines on 4 August to build 18 advanced spacecraft platforms for the Space Development Agency's Accelerated Missile Defense Tranche 3 mission. Intuitive Machines will manufacture and deliver the satellite platforms to host L3Harris' payload technology for national security space operations. L3Harris reported Q2 2026 revenue of $5.9 billion, an 8% year-over-year increase, with net income of $600 million. The company raised its full-year 2026 revenue guidance to $23.2 billion–$23.7 billion, backed by a $42.0 billion backlog. Intuitive Machines reported Q2 2026 revenue of $206 million, more than four times its prior-year level. However, the company posted an operating loss of $47 million and burned $84 million in cash during the quarter, leaving $367 million in cash. Its backlog expanded to a record $1.8 billion.

L3 Harris CEO ousted amid misconduct allegations, echoing 2012 Lockheed Martin exit

Christopher Kubasik has been ousted as CEO of L3 Harris following allegations of misconduct. According to Semafor, citing sources familiar with the matter, an investigation found he was engaged in an inappropriate relationship with a subordinate. This marks the second time Kubasik has been forced out of a leadership position under similar circumstances. In 2012, he was set to become CEO of Lockheed Martin but resigned after an ethics investigation confirmed he had a close personal relationship with a subordinate employee. L3 Harris, headquartered in Melbourne, Florida, announced Kubasik's departure on 17 August. The company said the misconduct was unrelated to financial reporting, controls, customer relationships or operational performance. Kubasik will retain some vested stock options but won't receive severance payments.

L3Harris CEO steps down after conduct review, shares fall 2.7%

L3Harris Technologies announced the immediate departure of CEO Christopher Kubasik following a conduct review, causing shares to fall roughly 2.7% in premarket trading Monday. The board appointed Sam Mehta as president and CEO, whilst Lewis Hay III became independent chairman. The company stated Kubasik's conduct was inconsistent with its Code of Conduct, though unrelated to financial reporting, controls, customer relationships, or operational performance. Following an investigation with independent counsel, the board entered into a separation agreement with Kubasik. Mehta joined L3Harris in 2023 and brings over 25 years of aerospace and defence leadership experience. He previously led segments comprising more than 80% of the company's total revenue. Despite the leadership change, L3Harris reaffirmed its 2026 consolidated revenue and financial guidance.

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.
