Cobham has received a contract modification worth $72m (£49m) from the US Navy to produce 51 ALQ-99 low-band transmitters (LBTs) and provide spare parts.
This contract, initially valued at $37m, was previously announced by the company in October 2008.
The LBTs are designed to protect strike aircraft, ships and ground troops by disrupting enemy radar and communications signals. Used aboard US Navy and US Marine Corps EA-6B aircraft, the LBTs currently support Operation Enduring Freedom and Operation Iraqi Freedom.
They will also be used by the US Navy’s newest airborne electronic attack platform, the EA-18G Growler.
The LBTs are manufactured at the Cobham Sensor Systems facility in Lansdale, Pennsylvania. To date, 120 LBTs – worth approximately $185m – have been ordered, with 40 already fielded.
