New Chain Gun Installation Aboard USS Ingraham

By Mass Communication Specialist 3rd Class Kat Corona, USS Abraham Lincoln Public Affairs

EVERETT, Wash. (NNS) -- USS Ingraham (FFG 61), of Destroyer Squadron 9 welcomed a new addition in July with the installation of the MK38 MOD II 25mm chain gun.

Ingraham is the first frigate in the fleet to receive the new system, but it has been utilized on other classes of Navy ships.

The new system, which was updated from the legacy MK38 MOD I 25mm, is completely automated and does not need to be fired manually like the old system. By taking legacy equipment still in the fleet and updating it to meet the ever-growing threats at sea, the Navy can perform duties more efficiently and effectively.

It uses a state-of-the-art electro-optical sight, a camera that can be used independently of the gun. It enables the operators to see tracks morethan 10,000 yards and uses a laser range-finder to measure the distance to a target, explained Ingraham's Electronics Material Officer and Assistant Combat Systems Officer Ensign Brandon Gilstrap, of Jacksonville, Ark.

The gun's mount is controlled in Ingraham's Combat Information Center (CIC) by the Remote Operator Console (ROC). The gunner sits at the ROC and tracks incoming vessels using the video from the mount. "The system is able to auto-track the oncoming vessel until the tactical action officer gives the gunner orders on the deployment of warning shots or direct fire," said Gilstrap.

This system enables Ingraham to defend the ship more effectively even with reduced manpower.

"It is an honor for Ingraham to be chosen as the test platform for the FFG class," said Gilstrap. "Our reputation for being 'the last and finest' has helped iron out the bugs for future FFG installations."
