Damen Schelde Naval Shipbuilding and launched in November 2018. HAS mode In 1998, a memorandum of understanding was signed by the defense departments of Germany and the United States to improve the system so that it could also engage so-called "HAS", Helicopter, Aircraft, and Surface targets. As developed, the HAS upgrade just required software modifications that can be applied to all Block 1 RAM missiles. SeaRAM weapon system The SeaRAM combines the radar and electro-optical system of the Phalanx CIWS Mk-15 Block 1B (CRDC) with an 11-cell RAM launcher to produce an autonomous system—one which does not need any external information to engage threats. Like the Phalanx, SeaRAM can be fitted to any class of ship. Due to the common mounting, SeaRAM inherits the relatively easy installation characteristics of its gun-based sibling, with Raytheon stating that SeaRAM "fits the exact shipboard installation footprint of the Phalanx, uses the same power and requires minimal shipboard modification". In 2008, the first SeaRAM system was delivered to be installed on . , one SeaRAM is fitted to each Independence-class vessel. In late 2014, the Navy revealed it had chosen to install the SeaRAM on its Small Surface Combatant LCS follow-on ships. Beginning in November 2015, the Navy will complete installation of a SeaRAM on the first of four s patrolling within the U.S. 6th Fleet. The SeaRAM will equip the Royal Saudi Navy's multi-mission surface combat (MMSC) based on the s.
