That rotating dome perched atop the AH-64 Apache attack helicopter does a lot more than just spin in the wind. It is the tactical brain that lets the world's most famous gunship peer over ridgelines while the rest of the aircraft stays completely concealed behind natural cover. When the U.S. Army hands out a massive nearly four-hundred-million-dollar contract to keep that radar system operational, military planners and defense contractors take notice.
Longbow LLC, the joint venture formed between Lockheed Martin and Northrop Grumman, just locked down a $419.6 million contract with the Army Contracting Command based at Redstone Arsenal in Alabama. The agreement covers production and sustainment of the AN/APG-78 fire control radar systems for both AH-64D and AH-64E fleets, with work scheduled to run through January 2032.

If you look at how modern combat aviation operates, radar sustainment is just as critical as building brand-new airframes. Aircraft parts wear out under extreme flight conditions, software needs continuous patches to counter evolving electronic warfare threats, and foreign militaries rely heavily on uninterrupted depot support to keep their own rotorcraft mission-ready.
Why The Mast Mounted Radar Changes Everything
Before the Longbow radar became standard equipment, attack helicopters had to expose a significant portion of their fuselage to acquire targets, leaving them vulnerable to ground fire and shoulder-mounted missiles. The AN/APG-78 system sits in its distinctive dome directly above the main rotor mast. Crews can hover behind a hill, a clump of trees, or a shattered building while the radar waves sweep the horizon. To read more about the context here, Wired offers an excellent summary.
The system automatically searches for, detects, locates, classifies, and prioritizes dozens of moving or stationary targets on land and sea simultaneously. Dust, heavy rain, thick smoke, or absolute darkness do not stop it. Software updates, specifically the Version 6 upgrade package, added specialized maritime modes for tracking vessels, enhanced single-target tracking, and expanded the overall detection range against ground and airborne threats.
This contract is not just about manufacturing brand-new hardware off an assembly line in Orlando, Florida. It is heavily weighted toward post-production support. That means program management, complex logistics tracking, depot-level module repairs, replenishment of spare parts, and specialized engineering training for the technicians who maintain these fleets in the field.
Global Reach And Foreign Military Sales
The Apache is a global export powerhouse, and the Longbow radar travels wherever the helicopter goes. The Qatar Emiri Air Force received the milestone 500th fire control radar unit back in 2020. Since then, the user base has expanded to include international operators like Morocco, the Netherlands, the United Arab Emirates, Australia, Kuwait, and the Indian Army.
Sustaining a global fleet of this size requires a massive supply chain network. Foreign military customers cannot afford to have grounded attack helicopters waiting months for spare radar electronic units or ground support equipment. This multi-year agreement gives Longbow LLC the financial runway required to stockpile depot spares and keep engineers deployed worldwide.
The Army solicited only one bid for this specific contract and received one, which makes sense given the proprietary nature of the technology. Lockheed Martin and Northrop Grumman own the technical data rights and the specialized manufacturing processes required to build and service the AN/APG-78 radar. No other defense contractor can step in and duplicate these radar components without years of reverse-engineering and billions in development costs.
Looking Ahead At Defense Procurement Trends
Defense budgets face constant scrutiny, but spending on proven front-line assets rarely dries up overnight. The U.S. Army continues to lean heavily on the AH-64E architecture while future vertical lift programs slowly work their way through development pipelines. Upgrading and maintaining legacy sensors ensures the current attack helicopter fleet remains lethal against modern peer adversaries.
Funding and specific work locations will be determined with each individual order placed under the umbrella of this contract over the next several years. Expect future task orders to cover ongoing electronic warfare updates as potential adversaries field more sophisticated radar-jamming and digital spoofing equipment. Keeping the Apache ahead of electronic countermeasures is a never-ending cat-and-mouse game, and contracts like this are the ammunition that keeps the technology sharp.
