USS Bataan commanding officer captain Gregory Leland said: “We, as a surface force repair enterprise, need to continue to push IMA-level repairs to Code 900 to rebuild our Sailor’s expertise, to give the operational commanders increased flexibility to more effectively repair ships, and support training and operations to increase the operational availability of our fleet.”

MARMC Diesel Shop Lead Supervisor George Tellefsen said: “We’re all skilled mechanics, but this was new to some of us. In our shop, you have diesel mechanics and gas turbine mechanics, and although we’ve worked on steam turbines before, we’ve never done a complete SSTG.”

The USS Bataan (LHD-5) amphibious ready group (ARG) completed its first surface warfare advanced tactical training (SWATT) exercise last week.

SWATT is intended to provide advanced tactical training to increase surface force lethality and tactical proficiency.

The exercise involved an in-port academic session and an underway training phase.

The Bataan ARG consists of USS Bataan, USS New York (LPD 21), USS Oak Hill (LSD 51), and embarked Helicopter Sea Combat Squadron 28 (HSC 28) and Naval Beach Group Two assets.
