The Government of Australia has also requested weapon load crew trainers (WLCT), practical explosive ordinance disposal trainers (PEST), containers, support, and ground crew test equipment.

Australia also seeks to receive site survey, transportation, warranties, repair and return, maintenance, publications and technical documentation, as well as personnel training and equipment. The country has also requested US Government and contractor representative engineering, logistics, and technical support services.

The proposed sale is expected to help the US’ non-Nato ally in developing and maintaining its self-defence capability while supporting the ongoing sale of the F-35A to the Royal Australian Air Force (RAAF).

“The GBU-53 / B SDB II is an air-launched, precision strike-guided weapon that can detect, track, and destroy stationary or moving targets with high-precision and stand-off range during the day and at night in all weather conditions.”

The equipment being procured will strengthen combined operations, particularly air-to-ground strike missions in all weather conditions, and increase interoperability between the US and the RAAF.
