USS San Antonio (LPD 17) Combat Systems Ship Board Qualifications

The amphibious transport dock USS San Antonio (LPD 17) fires the ship’s Rolling Air Frame Missile launcher for the first time during a live firing exercise. San Antonio and her crew are at sea conducting Combat Systems Ship Board Qualifications, in an attempt to see how well the ship’s Combat System’s Suite and ship’s weapons work together.

I haven’t heard much about the San Antonio’s performance so far. The ship had a troubled construction.

The RIM-116 Rolling Airframe Missile is a short-range IR missile primarily for defense against cruise and anti-ship missiles. A future generation of the Phalanx Block 1B CIWS will replace the 20mm gun with 11 RAM launchers for greatly increased range. The new system will be called the Sea RAM:

  1. Nice weapon! I didn’t know there was any defense against a cruise missile short of pointing a vulcan at it and crossing your fingers.

  2. Now that is a major leap forward. Being a dinosaur, I remember being drafted to be a safety officer on the both the forward twin 3’50’s on USS Austin LPD4 (which as I read somewhere is in for refitting and mods). It was a noteworthy day, trying to check gun site with binos while the guns were on radar control shooting at an aircraft towed target. The squids were a lot more eager to let fly, than I was to let them until I could see the aircraft and the towed target. Turns out the first ‘lock’ was on the aircraft not the target. We completed the exercise without going to jail, or having to explain to some Italian pilot’s mommie why we shot him down. The exercise actually ended early when the USS Independence fired a really neat bracket of shells a couple hundred meters directly off our bow. Game over, I’ll be in the Wardroom.
