ON Tuesday, the National Archives released the 1985 cabinet submission that led to the decision to build six Collins-class submarines in Adelaide. A key question is whether the lessons from that experience have been learned by the current government as it moves to buy a new class of replacement submarines for the navy. Continue reading

Norfolk-based submarine commander relieved

 USS Montpelier and USS Jacinto

The commander of the submarine USS Montpelier has been relieved after an investigation into a collision at sea that occurred off the Florida coast in October, the Navy announced Friday.

Cmdr. Thomas Winter was relieved due to loss of confidence in his ability to command, the Navy said. He has been reassigned to administrative duties at Submarine Force Atlantic in Norfolk.

Cmdr. Stephen Mongold will assume all duties as commanding officer of the Montpelier. Mongold previously served as executive assistant for the commander of the Submarine Force.

Capt. Blake Converse, commander of Submarine Squadron Six, relieved Winter

The Norfolk-based submarine collided with the guided-missile cruiser USS Jacinto during routine operations on Oct. 13. No one was injured in the mishap.

The main cause of the crash was “human error, poor teamwork by the Montpelier watch team, and the commanding officer’s failure to follow established procedures for submarines operating at periscope depth,” according to a Navy press release.

The investigation also revealed unspecified “contributing factors” that relate to training and oversight within Fleet Forces Command.

MoD: Trident submarines cannot be moved from Scotland to Plymouth

Devonport is ruled out as home for submarines, raising questions over future of fleet if Scotland votes for independence

Britain’s nuclear-armed submarines cannot be moved from Scotland to the Devonport naval base in Plymouth because they do not have safety clearances to dock there.

The disclosure has huge implications for the Ministry of Defence (MoD) if Scotland votes for independence and a new government demands the withdrawal of the nuclear fleet.

The MoD has revealed that the safety arrangements for Devonport do not permit the presence of submarines carrying Trident nuclear warheads. The MoD’s safety experts are not considering changing that.

The problem is that the dockyard is in a densely populated area and, if there were an accident, thousands of people would be put at risk. The worst accident scenario envisaged by the MoD would kill up to 11,000 people in Plymouth and would not meet the official criteria for what is acceptable, according to a new report.

The Scottish government, which is run by the Scottish National party, has said it would eject nuclear weapons from the Faslane submarine base on the Clyde as soon as possible after Scotland became independent. A referendum on Scottish independence is due to be held in the autumn of 2014.

Experts and politicians have repeatedly suggested that the Vanguard-class submarines that carry nuclear-tipped Trident missiles could be relocated to Devonport. In evidence to a House of Lords committee in December, the former head of the Royal Navy, Admiral Lord West, said “they could go there”.

But a response under freedom of information law from the MoD now indicates that will not be possible. The “safety case” it has drawn up for regulators to demonstrate that Devonport can be operated without undue risk rules out nuclear-armed submarines.

“Neither the Devonport naval base nor the Devonport dockyard, which is owned and operated by Babcock, safety case permit the berthing of an armed Vanguard class submarine,” the MoD said.

It also disclosed that its internal safety watchdog, the Defence Nuclear Safety Regulator, “has not provided any advice on the feasibility of docking of an armed Vanguard class submarine in Devonport dockyard”.

The MoD was responding to questions from the Scottish Campaign for Nuclear Disarmament (SCND), which wants to get rid of Trident altogether. “This shows that it is wrong to suggest that Trident can just move to Devonport if it is thrown out of Scotland,” said the campaign’s co-ordinator, John Ainslie.

A new report by SCND applies the MoD’s criteria for accidents at Faslane to Devonport. It concludes that Devonport would never be an officially acceptable location for Trident submarines because of the much greater population that would be put at risk.

There are about 166,000 people living within five kilometres of the Devonport base, compared with about 5,200 within that distance of Faslane. In assessing the dangers of a major accident at Faslane’s shiplift in 2000, the MoD concluded that the “societal contamination” that could result meant that “the risks are close to the tolerability criterion level”.

If a similar accident happened at Devonport, the MoD’s tolerability criteria would be massively exceeded, the SCND report says. If there was a light wind blowing from the south-west, it estimates that 800 people would be killed by leaking plutonium.

If the weather was calm, the report says that as many as 11,000 people could die from radiation poisoning. There would also be additional casualties from the blast, which could break windows across a quarter of Plymouth.

The MoD’s worst-case accident scenario assumes that all the conventional explosives in the eight Trident missiles carried by a single submarine detonate. It then assumes that all the plutonium in the missiles’ 40 nuclear warheads is dispersed, amounting to perhaps 160kg.

“A missile accident at Devonport, in the centre of Plymouth, could result in thousands of deaths,” said Ainslie. “In addition, a large proportion of the city would be abandoned for hundreds of years.”

The MoD stressed that the UK government was making no plans for independence, as it was confident that Scotland would not vote to leave the UK. “We are therefore not making plans to move the nuclear deterrent from HM Naval Base Clyde, which supports 6,700 jobs, and where all of our submarines will be based from 2017,” said an MoD spokesman.

“The government is committed to maintaining a continuous submarine-based nuclear deterrent and has begun the work of replacing our existing submarines.”

US Submarine Jefferson City wins Battle “E” award

Submarine Jefferson City wins Battle

USS Jefferson City, one of six Los Angeles-class attack submarines homeported at Point Loma, has received the coveted Battle Efficiency, or “Battle E” award, from the Commander Submarine Force, U.S. Pacific Fleet.

The Navy says the Jefferson City, which typically sails with 12 officers and 98 men, won the award because the 361-foot boat had the most proficient crew in its squadron, and “sustained superior technical performance and continual combat readiness throughout (2012),” the Navy said in a statement.

Commander Submarine Force, US Pacific Fleet also announced these other Battle “E” winners and their homeports.
