US Navy Mk38 gun systems to gain co-axial small-caliber machine gun


The U.S. Navy is installing a co-axial 7.62 mm machine gun on the mounts of its Mk38 chain gun systems, a Northrop Grumman official recently stated.

The co-axial Mk52 7.62 mm is gas-operated and uses recoil to eject spent cartridges and advance to the next round. A misfired round is safely ejected forward of the barrel as well, Jarrod Krull, communications manager for Northrop Grumman Armament Systems, said in an interview with Seapower.

The Mk38 Mod 2 gun mount includes a 25mm M242 Bushmaster rapid-fire cannon that fires an explosive round. The mount is automatic, gyro-stabilized and remotely operated, but retains the optional manual firing of the Mk38 Mod 1. The system has day and night sensors and a laser rangefinder.

The Mk52 7.62 mm is designed as a defence against small boats, aircraft and unmanned aerial vehicles for most U.S. surface warships and as a general-purpose gun for the Cyclone-class coastal patrol ships and Mk VI patrol boats.

Krull said the addition of the co-axial Mk52 machine gun gives the gunner another “right-sized” option for countering a small target, such as pirates or terrorists on jet skis. The Mk52 is very durable, reliable and accurate,” according to a Navy briefing slide. Northrop Grumman is installing the Mk52 guns in the Mk38 under an indefinite delivery/indefinite quantity contract.

The company also is offering the Navy another upgrade of the Mk38 by switching out the M242 Bushmaster cannon for a larger caliber weapon, the Mk44 30mm cannon, the same gun used as a close-in weapon on the San Antonio-class amphibious transport dock ship, the littoral combat ship’s surface warfare module and the Zumwalt-class guided-missile destroyer. Another option is the stretch version of the Mk44, which would allow the use of programmable ammunition, such has air-burst ammunition.
