Good deal on slightly used minesweepers, some assembly required

If you are in the market for some pre-owned warships, the Royal Australian Navy wants to make a deal. Working through a commercial service, the Navy advertised the HMAS Hawkesbury and HMAS Norman for sale “Sold As Is Where Is.”

The 172-foot long mine hunters have composite hulls designed to “flex inwards if an undersea explosion occurs nearby,” which is always a good thing.

Built in 2000 as part of a six-ship class to an Italian design (Lerici-class, the same as the U.S. Navy’s short-lived Osprey-class MHCs) both Hawkesbury and Norman were laid up in 2011 and have been in storage ever since while the other four ships have remained with the fleet.

Sadly, it looks like their DS30B 30mm Bushmaster cannons and M2 .50-cal machine guns have been removed, but the vendor offering them for sale suggests they could be turned into luxury yachts or charter vessels.

Not mentioned is a Jacques Cousteau/Steve Zissou-style recycle.

No price is listed but the vendor, Grays Online, does caution that the ships have had their shafts and propellers removed and would have to be towed off by the buyer, saying, “inspection is highly recommended.”

Congress not impressed with LCS mine hunting program

The Littoral Combat Ship is a sausage program that was envisioned to replace the Navy’s diverse minehunters/sweepers, frigates and patrol craft with 50+ ships on a single hull that could do it all (after all, any ship can be a minesweeper once, right?) through a series of plug-and-play modules.

Remote Minehunting System (RMS) to be used on the LCS, in theory

Well what we have almost 20 years into the program are two hulls (Freedom and Independence classes) that can do some of the same tasks as the frigates and patrol craft (except for ASuW or ASW against a modern opponent), but there’s a thing about that $706 million mine module program…

From USNI

At issue are recent reports on the reliability of a core component in the MCM package, the Remote Minehunting System (RMS) — comprised of the Raytheon AQS-20A towed array sonar and the Lockheed Martin remote multi-mission vehicle (RMMV).

The 7.25-ton semi-submersible RMMV — designed to deploy from the LCS and autonomously scout mines with the AQS-20A — in particular has had a history of persistent reliability problems.

SASC Chairman Sen. John McCain (R-Ariz.) and ranking member Sen. Jack Reed (D-R.I.) cite an early August memo signed by director of the Office of Test and Evaluation (DOT&E) Michael Gilmore that “assessed the current Remote Mine Hunting System and RMMV reliability as being 18.8 hours and 25.0 hours between mission failures… which is well below the Navy’s requirement of 75 hours” and that the Navy provided “no statistical evidence that the [system] is demonstrating improved reliability, and instead indicates that reliability plateaued nearly a decade ago.”

Worse, the Navy put their low-mileage Osprey-class coastal minehunter (with some hulls just being eight years old) on the chopping block back in 2007 (Taiwan, Egypt and Greece picked them up lighting fast) and is planning on retiring the Avenger-class mine sweepers and vaunted MH-53 Sea Dragon MCM helos in just a few years, making the LCS/MCM program “it” for U.S. Navy mine sweeping.
