U.S. Navy Conducts SeaRAM Firing Event Onboard USS Indianapolis

The U.S. Navy successfully conducted a SeaRAM (Rolling Airframe Missile) firing event onboard the USS Indianapolis (LCS 17) on July 16, scoring a mission success against its intended aerial drone target.

During this test event, the SeaRAM aboard the USS Indianapolis was employed to detect, track, and engage an inbound BQM aerial target drone and successfully intercepted it with the first and only missile launched. The success of this event indicates the capabilities of the ship in defense against an Anti-Ship Cruise Missile (ASCM).

This test firing was the first ever full-up demonstration of SeaRAM capability aboard the Freedom-variant Littoral Combat Ship (LCS). Structural test firing was successfully completed on this hull earlier in 2020.

SeaRAM is a MK15 Close-In Weapon System (CIWS) variant that integrates two Fleet proven weapon systems: the Block 1B Phalanx CIWS (a ship protection capability deployed on virtually all naval surface ships), and the previously deployed Rolling Airframe Missile (RAM) Guided Missile Weapon System.

The Freedom-variant LCS integrates the SeaRAM with the ship via the COMBATSS-21 combat management system. This milestone testing event was conducted during regularly scheduled Combat System Ship Qualification Trials (CSSQT) and is the result of long-term planning, predictive analysis, and assessment, modeling and simulation. In preparation, the Navy conducted several safety assessments across multiple organizations, coupled with extensive planning and training with the USS Indianapolis’ crew.

This demonstration of SeaRAM anti-ship missile defense system was coordinated between Program Executive Office Unmanned and Small Combatants (PEO USC) and Program Executive Office Integrated Warfare Systems (PEO IWS). PEO USC and PEO IWS operate in tandem to deliver integrated combat capabilities and systems for LCS and are cooperatively working to introduce new Lethality and Survivability (L&S) upgrades to the LCS program.
