Independence Class LCS = Surveillance Frigates

The 17 Independence-class variants of the littoral combat ship– including some carrying hybrid surface warfare and mine countermeasures systems and seeing much better availability after switching from contractor to sailor-performed maintenance– have been getting some more attention and love from the Navy lately.

“We’ll always be operating in and around the archipelagos, probably Ryukyus, the Philippines, and areas into the Philippine Sea behind it. It turns out it is highly survivable and highly effective when operating in the environment it was built for,” said COMSEVENTHFLT Vice Adm. Bill Merz, commenting that one “pretty much owned” the South China Sea during a period last year where COVID had sidelined other, more sophisticated assets.

“It is not blue water ship by any means but when you put it in the archipelago and you combine low signature and high-speed, it turns out it’s very hard to target, very hard to kill and it’s very effective with a thousand places to get gas,” said Merz.

With that, Craig Hooper in a piece at Forbes argues the class could (finally) be settling into its groove, and points to its perhaps best use– creating mobile “surveillance bubbles” to point the Big Battle Fleet at stuff to kill.

Properly kitted out, an Independence Class surveillance frigate can serve as an electromagnetic warfare threat, collecting everything from tactical targeting data to strategically relevant emissions. Potentially add in a Marine Corps reconnaissance element, and things could get interesting.

Hooper argues to upgrade the sensor package on the Indys, fill them with UAVs, and turn them into proper surveillance frigates, with doctrine to match.

He may be on to something.

Wouldn’t it be nice to see the LCS turn out to be something that can work?

Navy gives LCS’s minesniffer a thumb’s up (finally)

The Navy last week announced the completion of developmental testing for Raytheon’s AN/AQS-20C mine-hunting sonar system at Naval Surface Warfare Center, Panama City Division.

For these things:

PACIFIC OCEAN (Feb. 27, 2019) The Independence variant littoral combat ships USS Independence (LCS 2), left, USS Manchester (LCS 14), and USS Tulsa (LCS 16) are underway in formation in the eastern Pacific. Littoral combat ships are high-speed, agile, shallow draft, mission-focused surface combatants designed for operations in the littoral environment, yet fully capable of open ocean operations. As part of the surface fleet, LCS has the ability to counter and outpace evolving threats independently or within a network of surface combatants.

The presser:

The AQS-20C is the next generation of the AN/AQS-20 system designed to be incorporated into the Littoral Combat Ship Mine Countermeasures Mission Package. The system consists of four sonar arrays: two side-looking arrays; a gap-filler sonar array; and a forward-looking sonar array providing simultaneous detection, localization, and classification of bottom mines, close-tethered moored mines, and volume-moored mines.

The system delivers high-definition images of bottom mines, providing the operator with both range and contrast data that combine to form a three-dimensional image during post-mission analysis to aid in mine identification.

Developmental testing verifies that a system’s design meets all technical specifications and that all contract requirements have been met. During testing the Raytheon-developed towed sonar sensor conducted 12 underway missions in various operational modes and at different depths at four separate NSWC PCD test ranges. The missions were conducted aboard the test vessel M/V Patriot.

The AQS-20C will now be integrated with and deployed from the Mine Countermeasures Unmanned Surface Vehicle (MCM USV), a long-endurance, semi-autonomous, diesel-powered, all-aluminum surface craft that supports the employment of various mine countermeasure payloads. The MCM USV can be launched and recovered by the LCS, from other vessels of opportunity or from shore sites to provide minesweeping, mine-hunting, and mine neutralization capabilities. The MCM USV is currently undergoing developmental testing as a component of the Unmanned Influence Sweep System at the South Florida Test Facility in Fort Lauderdale, Florida.

Test results will now undergo scoring and performance assessment leading up to a final developmental testing report that is expected to be completed in the spring. Findings from this report will be used for future performance improvements of the system.
