US 'taken aback' by HMS Astute (British sub)

US 'taken aback' by HMS Astute

06 March 2012

The United States Navy was 'blown away' by the performance of HMS Astute during sea trials in the Atlantic recently, the ship's commanding officer has said.

Commander Ian Breckenridge, 45, led HMS Astute through four-and-a-half months of sea trials off the US east coast and said the submarine had demonstrated "tremendous capability".

"We met and surpassed every expectation. She is just better than any other submarine I have ever been on," he said.

During the trials, Astute took part in simulated battles with American Virginia Class submarine USS New Mexico, deep dived, and fired her Tomahawk missiles and Spearfish torpedoes. HMS Astute sailed 16,400 miles during the deployment.

The success comes after a series of operational setbacks during the submarine's sea trials to date, with Astute becoming grounded on a shingle bank in late 2010 and later damaged by a tug sent to recover her. The attack submarine also suffered a failure of support systems in February 2011.

"Astute is still on trial and she is first of class, which always brings its own problems, but we are beginning to look beyond those problems and see the promise," said Commander Breckenridge, who previously served on HMS Superb and HMS Tireless.

"We fired off four Tomahawks, aimed at a corner of Eglin Air Force Base to test for accuracy, and we fired six Spearfish torpedoes, including the first salvo firing by a British submarine for 15 years.

"Our sonar is fantastic and I have never before experienced holding a submarine at the range we were holding USS New Mexico. The Americans were utterly taken aback, blown away with what they were seeing."

Second in class HMS Ambush was launched in 2011 and is set to begin sea trials later this year. The UK is to receive seven Astute class submarines overall.

I was reading “Scorpion Down”, and the author said that one could visualize the amount of ocean accessible to modern submarines by standing in a room with an 8 foot ceiling, and putting the head of a match against the ceiling.

Anything above the bottom of the match was accessible by submarines.

Wow...I did some quick math, and that came out to around 500 feet. Perhaps that was 1968 submarines, or maybe someone just got lazy and used the “excess of 500 ft” statement.

Boat I was on in the 1970’s was:

Displacement: 4,309 tons, Length: 292 ft, Beam: 32 ft

Looks like the moved the torpedo room back up to the nose.

I left New London in 1988 to go to my final tour in a Submarine Squadron in San Diego. I just looked it up, and she was commissioned USS VIRGINIA (SSN-774) on October 23, 2004. That surprised me because they were beginning to build it before I left Groton. As my aging memory returns, the sonar example I gave was for the Ohio Class boats and the info given out at that time was that the Virginia Class at full throttle was quieter than the Ohio Class tied to the pier.

Thanks for the comeback.

I always had it in my head that in subs the crew hotracked. (I’m an Army guy, so help me out on this....)

When I was in we did hot rack. At least 1/3 of the crew was on watch (operating the ship) at any given time so the junior folks would have two bunks assigned to three people. When you got off watch you just hopped into whichever one of the two were empty (and it may still be warm...thus the term "Hot Rack").

The nuke boats were a lot better with accomodations than the diesels. They retired the last diesel boat the day after I retired (I guess there just wasn't anyone left to run it).

I'm sure that there are plenty of FReepers who can set me straight, but I've got a buddy who used to be a civvie contractor on the Permit-class subs.

He said that they were officially rated to "in excess of 30 knots and in excess of 300 feet". His commentary on that? "Yeah.....right."

Those were fast boats. I think that I'd rather be invisible than fast, though.

By the way it was with full respect. You’ve done things most of us probably couldn’t imagine, and know things that are still classified. It is an honor. God bless.

Exactly. We have (or had) pretty good boats...I’d still take ours if I had to fight in a sub, as long as the crew came with it...:)

If that is, indeed CGI, I want to check out both the modeling and rendering apps!

BTW, the only thing "hokey" I see is the waterline. Water wets things -- and water with waves never shows a straight line interface...

Me too. I did a doubletake when I saw that.

Actually “defence” is the correct “English” spelling.
