In this video we join sailors in the 26th Marine Expeditionary Unit on board the USS Kearsarge as they conduct a live-fire exercise with the monstrously powerful Mk38/M242 Bushmaster.
Manufactured by McDonnell Douglas since 1981, the M242 is a double-loaded electric drive cannon firing 25 x 137 mm rounds. The Mk38 is the naval version of the cannon that can be mounted on anything from a patrol boat to an aircraft carrier.
The exercise below is the last step required in a 6-month long pre-deployment training program with the MEU.
