HMS Urge, found on eternal patrol

HMS Urge, IWM FL 3433

Commissioned 12 December 1940, the British U-class submarine HMS Urge (N 17) served in World War II throughout 1941, seeing extensive action in the Med. Over the course of 20 patrols, she proved a one-submarine wrecking crew to the Italian Navy, sinking the Giussano-class light cruiser Giovanni delle Bande Nere as well as extensively damaging the cruiser Bolzano and battleship Vittorio Veneto.

On 27 April 1942, the 16-month-old Urge left Malta en route to Alexandria but failed to arrive on schedule and was reported overdue on 7 May. Her crew, commanded by LCDR Edward Philip Tomkinson, DSO and Bar, RN, was never heard from again.

Her shield, which had been landed prior to shipping out, is currently on display at The Register Office in Bridgend, Wales. The town, which contributed around £300,000 to the war, had adopted HMS Urge as part of national “Warship Week” in 1941.

HM Submarine Urge was discovered in a search conducted by staff from the University of Malta just off Malta’s Grand Harbour, where she apparently was destroyed on the surface by a mine. In addition to her 32 crewmembers, she had been carrying 11 other naval personnel and a journalist.

Queen City, Fifth Edition

The fifth U.S. Navy warship built for the first city constructed after the War of Independence was commissioned into the Fleet this weekend.

All photos: Chris Eger, feel free to share. Note that big bow thruster marking and the fact that she is drawing under 5m. 

USS Cincinnati (LCS-20), an Independence-class littoral combat ship, follows on the heels of a Los Angeles-class SSN, two cruisers (more on that later) and a City-class ironclad gunboat that was sunk and raised twice during the Civil War. This, of course, all befits the mold of storied Roman statesman and military leader Quintius Cincinnatus.

I attended the ceremony– which had Adm. Jamie Foggo (COMNAVEUR-NAVAF) in attendance, who spoke eloquently about Cincinnatus and, in the end, broke his flag aboard the Navy’s LCS– met her crew and toured the vessel.

For a 420-foot/3,100-ton frigate-sized (although not frigate-armed) warship, the wardroom is small.

Her skipper and XO are both CDRs, while OPS is an LCDR. Ten O2/O3s flesh out the rest of the departments (NAV, CSO, 1stLT, EMO, Weaps, Ordnance, Chief Engr, Main Prop Aux, Aux, Electrical). There are 25 Chiefs including an HMC who serves as the ship’s independent duty corpsman. The rest of the crew is made up of just 33 ratings and strikers. This totals 71 souls, although it should be noted that some of those were from other LCS crews. Notably, Crew 214 recently commissioned a previous Independence-class LCS only months ago.

Of interest, her first watch was just four-strong (including two minemen) with just two watchstanders on the bridge.

A few other things that struck me was the size of the payload bay on the trimaran– the ship has a 104-foot beam, more than twice that of the FFG7s!– which was downright cavernous for a ship that could float in 15 feet of brownish water. This translates into a helicopter deck “roof” that is the largest of any U.S. surface warship barring the Gator Navy and, of course, carriers.

One thing is for sure, you can pack a lot of expeditionary gear and modules in here.

She also has a lot of speed on tap, packing 83,410 hp through a pair of (Cincinnati-made) GE LM2500 turbines and two MTU Friedrichshafen 8000 diesels pushing four Wartsila waterjets. She is rated capable of “over 40 knots” although Foggo noted with a wink she could likely best that.

She has a 3200kW electrical plant including four generators and an MTU 396 TE 54 V8 prime mover.

Sadly, she doesn’t have a lot of firepower, limited to topside .50 cals, her Mk-110 57mm Bofors and C-RAM launcher.

She is expected to be optimized for mine countermeasures with the MH-60-based ALMDS and AMNS systems along with an Unmanned Influence Sweeping System (UISS) and AN/AQS-20A mine detection system. She has a missile deck for the new Mk87 NSM system, although the weapon itself is not currently installed.

Still, should she be headed into harm’s way, I’d prefer to see more air defense/anti-missile capabilities installed, but what do I know.

USS Cincinnati will join her nine sister ships already homeported in San Diego: USS Independence (LCS 2), USS Coronado (LCS 4), USS Jackson (LCS 6), USS Montgomery (LCS 8), USS Gabrielle Giffords (LCS 10), USS Omaha (LCS 12), USS Manchester (LCS 14), USS Tulsa (LCS 16) and USS Charleston (LCS 18).

Built just at Austal’s Alabama shipyard, an hour away from where she was commissioned, five sisters are currently under construction in Mobile. Kansas City (LCS 22) is preparing for sea trials. Assembly is underway on Oakland (LCS 24) and Mobile (LCS 26) while modules are under production for Savannah (LCS 28) and Canberra (LCS 30), with four more under contract through to LCS 38.

‘The ships that the Navy forgot’

Pro Publica had this take on the Navy’s current state of minesweeper deficit with the protracted LCS mine countermeasures systems still a long ways off and the Avenger-class ships getting the short end of the readiness dollar.

It’s actually pretty interesting.

The U.S. Navy officer was eager to talk.

He’d seen his ship, one of the Navy’s fleet of 11 minesweepers, sidelined by repairs and maintenance for more than 20 months. Once the ship, based in Japan, returned to action, its crew was only able to conduct its most essential training — how to identify and defuse underwater mines — for fewer than 10 days the entire next year. During those training missions, the officer said, the crew found it hard to trust the ship’s faulty navigation system: It ran on Windows 2000.

The officer, hoping that by speaking out he could provoke needed change, wound up delaying the scheduled interview. He apologized. His ship had broken down again.

“We are essentially the ships that the Navy forgot,” he said of the minesweepers.

Limpet mine update: ‘With high confidence’

U.S. Navy CDR Sean Kido, head of Explosive Ordnance Disposal Mobile Unit One One (EODMU 11) explains the attack on the Panama-flagged chemical/oil tanker Kokuka Courageous (19,349t) and the Norwegian-owned (International Tanker Management) Marshal Islands-flagged oil tanker Front Altair, allegedly by Iran’s Revolutionary Guard, in the Gulf of Oman on June 13th, 2019:

Boom!

With the premature scrapping/disposal of the 12 Osprey-class mine hunters (which only had a decade on their hulls when put out to pasture), the now 11-ship (out of 14 built) Avenger-class are all that is left of the dedicated U.S. counter-mine vessels. Of course, the Mine Counter-Measures Modules of the Littoral Combat Ships currently in commission are expected at any time. (Holds breath. Turns blue.

(Or approximate)

The attack in International waters hit the Panama-flagged chemical/oil tanker Kokuka Courageous (19,349t), owned by Singapore-based Bernhard Schulte Shipmanagement (BSM) and carrying a load of methanol; along with the Norwegian-owned (International Tanker Management) Marshal Islands-flagged oil tanker Front Altair (62,849t) with a load of crude, early on June 13. Both were carrying what Japan’s Trade Ministry says were “Japan-related” cargo.

The attacks occurred off the Emirati port of Fujairah, also on the Gulf of Oman, approaching the Strait of Hormuz, the narrow mouth of the Persian Gulf through which a third of all oil traded by sea passes.

Kokuka Courageous Front Altair

“The timing was considered sensitive as Japanese Prime Minister Shinzo Abe was visiting Iran on a high-stakes diplomacy mission.”

5th Fleet’s release on the matter through CENTCOM:

TAMPA (NNS) — U.S. Naval Forces in the region received two separate distress calls at 6:12 a.m. local time from the motor tanker (M/T) Altair and a second one at 7a.m. local time from the M/T Kokuka Courageous.

Both vessels were in international waters in the Gulf of Oman approximately 10 nautical miles apart at the time of the distress calls. USS Bainbridge was approximately 40 nautical miles away from the M/T Altair at the time of the attack and immediately began closing the distance.

At 8:09 a.m. local time a U.S. aircraft observed an IRGC Hendijan class patrol boat and multiple IRGC fast attack craft/fast inshore attack craft (FAC/FIAC) in the vicinity of the M/T Altair.

At 9:12 a.m. local time a U.S. aircraft observes the FAC/FIAC pull a raft from the M/T Altair from the water.

At 9:26 a.m. local time the Iranians requested that the motor vessel Hyundai Dubai, which had rescued the sailors from the M/T Altair, to turn the crew over to the Iranian FIACs. The motor vessel Hyundai Dubai complied with the request and transferred the crew of the M/T Altair to the Iranian FIACs.

At 11:05 a.m. local time USS Bainbridge approaches the Dutch tug Coastal Ace, which had rescued the crew of twenty-one sailors from the M/T Kokuka Courageous who had abandoned their ship after discovering a probable unexploded limpet mine on their hull following an initial explosion.

While the Hendijan patrol boat appeared to attempt to get to the tug Coastal Ace before USS Bainbridge, the mariners were rescued by USS Bainbridge at the request of the master of the M/T Kokuka Courageous. The rescued sailors are currently aboard USS Bainbridge.

At 4:10 p.m. local time an IRGC Gashti Class patrol boat approached the M/T Kokuka Courageous and was observed and recorded removing the unexploded limpet mine from the M/T Kokuka Courageous.

The U.S. and our partners in the region will take all necessary measures to defend ourselves and our interests. Today’s attacks are a clear threat to international freedom of navigation and freedom of commerce.

The U.S. and the international community, stand ready to defend our interests, including the freedom of navigation.

The United States has no interest in engaging in a new conflict in the Middle East. However, we will defend our interests.

The attack comes a month to the day after what is described as “Coordinated teams of divers using limpet mines incapacitated the vessels in a series of timed detonations” to damage four tankers from the Emirates, Saudi Arabia and Norway off the Emirati coast.
