What believers are saying

  • July 2026 backlog hit $42 billion after $7.3 billion orders and raised guidance.
  • June 2026 Camden groundbreaking expands PAC-3 capacity as missile inventories stay depleted.
  • August 2026 Intuitive Machines contract deepens L3Harris's SDA Tranche 3 missile-defense platform.

What critics are saying

  • Christopher Kubasik's August 2026 ouster exposed governance fragility and succession disruption.
  • Aerojet Rocketdyne integration and Camden expansions must execute flawlessly before 2030 demand spikes.
  • Lockheed and Pentagon pricing pressure can compress margins if delivery slips or defects emerge.

What makes L3Harris Technologies unique

  • PAC-3 and THAAD propulsion make L3Harris irreplaceable in U.S. missile defense.
  • Space & Mission Systems plus Missile Solutions give Sam Mehta 80% revenue control.
  • Roman telescope optics and NGI motors show unmatched breadth across space and interceptors.

L3Harris wins $121M in US Army orders for low-cost data radios

L3Harris Technologies has received production orders worth a combined $121 million from the US Army for its Low-Cost Data Radio (LOCODA) solution. The radio supports Army Command and Control needs. LOCODA reuses existing vehicle installation kits to field an upgraded communications system. It gives battlefield commanders access to command applications through several transport options on one platform, with minimal training. "The program leverages existing installation kits and enables them to support new and emerging requirements, saving the Army time and money," said Chris Aebli, president of Communications & Spectrum Dominance at L3Harris. The radio supports narrowband and wideband waveforms, anti-jam capabilities, and low probability of intercept and detection waveforms.

L3Harris wins $876M Navy contract for next generation jammer prototypes

L3Harris Technologies has won an $876 million contract modification from the US Navy for its Next Generation Jammer Low Band (NGJ-LB) program. The company will build prototype hardware, assemble specialised manufacturing equipment, and support flight testing. The award is undefinitized, meaning work starts before final price and delivery terms are agreed. The government typically uses such awards when it needs a project done quickly. The programme will replace ageing equipment that disrupts low-frequency radar and communications used against US combat aircraft. Chris Aebli, president of communications and spectrum dominance at L3Harris, said the company is "moving fast to deliver a system that equips aviators to counter those threats from safer, extended distances." The deal is small next to L3Harris's nearly $22 billion in revenue last year.

HGT Law investigates L3Harris after CEO Kubasik exit sent shares down 4.61% to $278.38

HGT Law is investigating L3Harris Technologies (NYSE: LHX) for possible securities law violations and breaches of fiduciary duty by its officers and directors. On August 17, 2026, L3Harris said Christopher Kubasik had stepped down as chairman and chief executive officer, citing conduct that breached its Code of Conduct. The stock fell $13.44, or 4.61%, to close at $278.38. The Wall Street Journal reported on August 19, 2026 that multiple women had raised concerns about Kubasik years earlier, including a formal harassment complaint around 2023. In 2012, Lockheed Martin asked him to resign as president over a relationship with a subordinate. The firm is examining whether L3Harris made misleading statements or withheld material information, and whether its board failed in overseeing executive conduct and approving Kubasik's separation terms.
