The Block 2 missile employs an active and semi-active guidance system, which are used to meet both current and emerging threats.

The current modification project is launched by NSWC PHD to support its ‘In-service Engineering Agent (ISEA) of the Future’ scheme.

NSSMS customer advocate and programme manager Robert Barrett said: “The modification, known as MIN MOD, will include an overhauled launcher that will bring together all of the programme elements to prove and verify required changes, as well as demonstrate that the change is fleet ready.

“The replacement launcher had to have the ability to be able to fire the ESSM Block 2.”

“This also provides the ISEA with the latest launcher that is in the fleet, allowing us to better execute our jobs in both fleet support as well as obsolescence management.”
