Northrop Grumman wins $56 million deal to upgrade Triton surveillance drone

Key Takeaways

• A $56 million Navy contract covers installation of a B7 upgrade kit on one Triton drone

• The Navy has not confirmed whether the upgrade adds IFC-4 signals intelligence capabilities

• Work will run through May 2030, primarily in Palmdale and San Diego

Northrop Grumman will upgrade a single U.S. Navy MQ-4C Triton maritime surveillance drone under a nearly $56 million contract modification awarded on October 28.

The work covers installation of a B7 retrofit material kit and is scheduled for completion in May 2030.

Naval Air Systems Command awarded the firm-fixed-price modification without competition, committing the full $55,986,538 from fiscal 2027 aircraft procurement funds.

The announcement does not identify the aircraft receiving the kit or explain what equipment, software, or capabilities the installation will change.

Upgrade details remain undisclosed

Northrop Grumman will perform 64 percent of the work in Palmdale, California, whereTriton aircraftare built. Another 34 percent will take place in San Diego, with the remaining 2 percent distributed across other U.S. locations.

The B7 designation follows the numbering used for individual Triton airframes in earlier contracts.

However, the Navy has not confirmed whether this installation will bring the aircraft to the Integrated Functional Capability 4 standard, commonly called IFC-4.

Previous contracts explicitly identified that configuration. A 2023 award worth $83.1 million covered upgrades to air vehicles B9 and B10, along with a main operating base, to the multi-intelligence standard.

The latest contract also resembles earlier work on air vehicle B5. In late 2025, the Navy exercised a $45.75 million option covering engineering, tooling, and labor to complete IFC-4 changes on that aircraft.

That work had the same geographic split and a June 2029 completion target.

Sensors expand Triton’s intelligence role

IFC-4 introduced signals intelligence capabilities to Triton through additional sensors for electronic intelligence and communications intelligence, according toNorthrop Grumman.

The sensors brought stricter requirements for protecting collected data, prompting hardware and software changes across the aircraft and its ground systems. The Navy first flew a Triton in the IFC-4 configuration on July 29, 2021.

Other surveillance equipment includes the AN/ZPY-3 Multi-Function Active Sensor, an X-band electronically scanned radar mounted beneath the fuselage, and the Raytheon AN/DAS-3 electro-optical and infrared turret.

Triton’s structure also differs substantially from theRQ-4 Global Hawkon which it is based. Northrop strengthened the airframe and wings and added de-icing equipment and lightning protection.

Those changes allow the unarmed aircraft to descend from approximately 50,000 feet to around 10,000 feet to identify ships before returning to its higher patrol altitude.

Further fleet changes take shape

The latest contract follows another October order worth $66 million to install 17 U.S. Navy and 16 Australian engineering changes on operational Tritons.

Separately, Naval Air Systems Command posted an October 22 notice outlining plans for a sole-source contract with Northrop Grumman covering engineering, software and cyber sustainment, logistics, and engineering change proposals.

Thatproposed agreementwould support both the U.S. Navy and Royal Australian Air Force, with an award expected in the third quarter of fiscal 2027.

Australia acquires Tritons through a cooperative program covering development, production, and sustainment.

Meanwhile, the B7 installation remains narrowly defined in the public announcement: a funded upgrade to one aircraft, with its precise technical scope and resulting configuration still undisclosed by the Navy.
