US Marine Corps modifies weapons loader adapter for F-35B

By Pat Host |

The US Marine Corps (USMC) modified support equipment to allow the guided bomb unit (GBU)-49 munition to be used on the Lockheed Martin F-35B Lightning II Joint Strike Fighter (JSF) short take-off and vertical landing (STOVL) variant.

When the USMC chose GBU-49 for the F-35B, it needed a piece of support equipment to load the weapon onto the aircraft. However, the conduit on the weapon did not fit the current weapons loader until a team from Naval Air Warfare Center Aircraft Division (NAWCAD) Lakehurst, New Jersey, modified the adapter, the ADU-894A/E, and delivered it on schedule to the USMC in November, according to a US Navy (USN) statement.

The NAWCAD Lakehurst Airborne Weapons Support Equipment (AWSE) branch was tasked to develop an adapter that could not only provide loading capability for the GBU-49, but for all MK-82 smart bombs to be loaded on the F-35B. The goal was to develop, test, build, and deliver the adapters within nine months.

John Peterson, project lead, said on 20 March that GBU-49 is part of the Enhanced Paveway II family of smart bombs. A wiring conduit is mounted externally on the body, enabling the weapon’s nose seeker to communicate with the tail guidance system when in flight.
