Test 12 unclassified, from the Fiscal Year 2016 budget, testing for Block 2 upgrades of the RAM (rolling airframe missile) for defense from incoming missiles to protect the fleet, testing done along with the Phalanx gun system (with the “R2D2” shaped enclosure) for the zone closest to the ships: close-in-weapon (CIW) defense. This test included LSD Navy ships, a different class than the LPD USS San Diego at the beginning of this thread, but similar purpose, amphibious warfare.
