Cobham has delivered the 100th low-band transmitter (LBT) to be used as part of the US Navy’s AN/ALQ-99 tactical jamming system.

The LBT is designed to protect strike aircraft, ships, and ground troops by interrupting enemy radars and communications.

The transmitter will also be carried on US Navy EA-6B Prowler and EA-18G aircraft and marine corps EA-6B aircraft, and used for operations in Iraq and Afghanistan.

The company was awarded a $46m contract in April 2010 from Naval Air Systems Command (NAVAIR) for a third lot of the LBT Antenna Group bringing the total number of units to 217 of the 315 required transmitters.

The low-band transmitter-antenna group (LBT-AG) has been in production since 2005.
