(Washington, D.C.) The Navy is now qualifying a new combat system for its Littoral Combat Ship intended to better integrate, streamlining and improve weapons on board the ship, a plan which is leading the service to prepare for a larger number of upcoming live-fire exercises to prepare the ship for major maritime warfare.

“We are undertaking a large-scale effort to upgrade combat systems, Capt. Jason Kipp, program manager, PEO Integrated Warfare Systems, told an audience at the Navy League’s Sea Air Space Symposium.

Part of the effort includes an introduction of new Government Furnished Equipment likely intended to improve fire-control, targeting and integration across a group of ship-board weapons systems. 

These weapons include an over-the-horizon Naval Strike Missile, Close-in-Weapons System for near-in threats and mid-range defensive interceptors such as SeaRAM and Rolling Airframe Missile. 


Over the course of many years of development, the SeaRAM missile has engaged and destroyed an aerial drone, Navy officials said. This was the first shipboard firing of the new weapon, which emerged from extensive planning, assessment, modeling and simulation, Navy officials said.

Kipp said the Combat Systems Qualification for LCS 19, the USS St. Louis, recently completed by firing a remote-controlled aerial targeting with SeaRAM and only the second second “full-up-display” of SeaRAM detecting and engaging from aboard the Freedom variant of the LCS. 

All of these weapons enhancements are intended to help establish the technological infrastructure sufficient for massive LCS “survivability and lethality upgrades” planned for 2023, Kipp said.

The CIWS ship self-defense weapon uses a Phalanx gun able fire 4,500 small projectiles per minute to blanket an area; the SeaRAM weapons replaces the gun with larger, longer-range Rolling Airframe Missiles….Unlike the CIWS weapons which, as an area-defense weapon, uses a 20mm cannon to shoot down threats close to a ship, SeaRAM fires a Rolling Airframe Missile (RAM) from an 11-missile battery, Raytheon officials explained.

The Rolling Airframe Missile is what defense experts call a “fire and forget” missile, meaning it uses an RF or radio frequency detection technology along with a heat-seeking infrared sensor to find its way toward an approaching threat in order to intercept and destroy it.

Navy destroyers would likely use a Standard Missile-3, or SM-3 to defend against an attacking long-range ballistic missile threat flying through space toward a target. 


The SM-6® missile is three missiles in one. It's the only weapon that can perform anti-air warfare, ballistic missile defense and anti-surface warfare missions. The system offers navies more flexibility in limited ship space—and it’s enabling the U.S. and its allies to cost-effectively increase the offensive might of surface forces.

Medium range anti-ship missiles or sea-skimming enemy rockets could be destroyed by an SM-2 or SM-6 interceptor. Threats a bit closer could be taken out by an Evolved Sea Sparrow Missile, or ESSM, or SeaRAM before a Close-In-Weapons-System strikes down approaching fire.

Distributed Maritime Operation

Arming destroyers and the Littoral Combat Ship with more lethal, precise and longer range weapons can easily be interpreted as being part of the Navy's larger "distributed lethality" strategy which first emerged in 2015 as part of an effort to massively arm the surface fleet. 

Since that time, the strategy has evolved and migrated into what the service calls “Distributed Maritime Operation,” a term perhaps indicating that newer networking, AI-enabled computing and cross-domain operations are inspiring the Navy to migrate or further develop its surface warfare strategy.

Broadly speaking, the idea is to help the Navy return more fully to a focus on "blue water" combat against potential "near-peer" adversaries following a decade of ground wars wherein the Navy expended more effort on things like counter-piracy, Visit Board Search and Seizure and counter-terrorism.
