The Ministry of Defence (MoD) has revealed that boats 4-7 of the Astute Class submarine are now £838 million over budget. The news came in their annual Finance and Economics Bulletin. 

The Astute class are the largest and most advanced attack submarines ever operated by the Royal Navy, combining world leading sensors, design, and weaponry in a versatile vessel. It is the replacement for the Trafalgar-class that entered service in the 1980s.

The class has frequently been cited as one of the most advanced submarines ever made. Indeed during HMS Astute’s sea trials in 2012, Commander Iain Breckenridge said he had “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”

According to the MoD UK Maritime Power doctrine, the Astute class:

‘provide the principal sea denial capability due to having both anti-submarine and anti-ship systems. When combined with an appropriate land attack missile, such as the Tomahawk, SSNs have a power projection capability of considerable range and penetrability, with important uses for deterrence and coercion’

In the MoD annual Finance & Economics Bulletin (found here), it was evident that boats 4-7 were well over-budget.

An MoD communications officer quoted the current costs for boats 4-7 to me as:
‘At approval, expected forecast cost to completion: £5,859M
Current forecast cost to completion: £6,697M’

That’s a 14% increase. For the purpose of perspective, the £838m over-budget sum could pay for 3 Type 31e frigates at the £250m per ship requirement price.

It should be noted that whilst the Astute class is over budget, it remains cheap in comparison to other similar classes:

  •  US Virginia class: £2.0B
  •  French Shortfin Barracuda class: £2.4B

Initial budgets should be more realistic and the same for contingencies. The blunt truth means the RN needs these subs going forward and, in some cases, their cost is immaterial in times of crisis.

Looking at most of the programmes, the MoDs initial budgets are generally accurate. The problems started decades ago at the initial design stage, and the peace dividend at the end of the Cold War killed any urgency in sub building after the Vanguards. BAE’s inexperience with the 3D design software they were touting also caused innumerable issues until they brought in an American who’d used it before. It’s unfortunate that a better contract wasn’t negotiated at the time so that the builder covers costs related to build issues, but that appears to be in the past after recent procurement disasters

the news that a swedish conventional submarine(costing 100 million) pierced an entire modern u.s carrier screen and carried out a 4 torpedo simulated attack on a u.s carrier. this submarine, conventionally powered. costing just 100 million compared to the astute is 14 times cheaper. a submarine costing roughly the price of 1 f-35 shows yet another example of the rudderless disjointed thinking in u.k naval procurement 14 submarine instead of 1 astute? speaks for itself.

Please update when we will be building an additional five irrespective of cost increase and the installation of supercavitating torpedoes. We need both in numbers.

Assuming the money is split between all departments based on budgets, the MoDs share only comes to roughly about £800mn. Even in a dream world where the MoD got a far bigger share, where would they be built? Barrow has boats 4-7, then it needs to build the Dreadnoughts. By the time there is capacity to start building attack subs again, it’ll be the 2030s and HMS Astute will be at the end of her 25 year life and in need of replacement. The only chance for expansion of the submarine fleet will either be in the future when the… Read more »

One serious issue is the building capacity. We have just one centre of excellence…Barrow! The idea of any additional Astutes out of that plant is a nonstarter. The Dreadnoughts will take over the majority of the building floor for some years to come. Any possibilities of contracting another yard to build Astutes would prove to be a very time-consuming exercise. Teaching a whole new build team would possibly take years before one piece could be made. Centralising excellent has huge cost dividends, but can result in very limited options beyond confirmed contracts.

What £39b are you talking about?

If this was for boats 1, 2 or even maybe 3 I wouldn’t be so surprised since change orders might be required in early builds as issues are discovered either during build or during the sea trials and/or early deployments of the first and perhaps second in class but at boats 4 through 7 is the design really not stable? And if these cost overruns are not coming from design change orders being implemented then where are they coming from? If it’s just general cost overruns and not a result of change orders initiated by the MoD then why is… Read more »

This is what I was thinking. I can fully understand cost overruns on the first couple of boats as I think the initial budgets are always too tight and never properly account for problems and adjustments to designs and requirements. However I can’t understand how the later boats are going over budget.

Depreciation of the Pound since the Brexit Referendum result, many defence components are bought in dollars and so costs have risen. Its affecting other defence procurement projects as well.

Most projects have a fixed exchange rate that is a lot higher than the actual national exchange rate to take out such fluctuations. The A400 project exchange rate had ,I think, some 20% float built into it.
So I reality if the national currency rises or falls it doesn’t matter to much

I recall the QE were delayed around 2008 and by pushing the project to the right to save money then the project increased by 1 billion or so. Nice work.

Same with the Astute. We need firm commitments and long term building for continuity.

Instead. Defence is a political football, kicked between two equally useless teams in the Tories and Labour as far as defence is concerned.

This countries political establishment need a major kick up the arse. Sadly a major war may end up being that kick.

That decision saved £100m in year, but cost £1.5bn… Then Dr. Liam Fox added in another £150m cost due to him thinking about getting F-35C instead of B, before someone managed to stop him…if he’d been allowed to proceed it would have cost billions. Admittedly we did manage to get £100m from the French for access to CVF design that they eventually backed away from. Everyone knew that the QE Class were quoted at far too low a price. Everyone knew that the price would rise from the original baseline, it was all designed to get it past the Treasury.… Read more »

Whilst funds are very tight I’m surprised that Boats 4-7 have an increase in cost,its usually the case that later builds tend to be significantly cheaper,perhaps there were some major issues in the supply chain.I hope the MOD learn from the Astutes and keep the building cycle of Submarines continuous rather than leaving gaps which impacts Skill retention etc.A blank cheque approach is never a good idea for a programme of this size but presuming the quoted costs of a Virginia and a Barracuda are correct the Astutes do seem rather good value.

The Astute class is amazing value for money. They are superior strength kdubmarines compared to Virginia and Barracuda classes. £800 million is small change to a government that gives £15 billion away per year on foreign aid and a soon to be paid £39 billion divorce bill to the EU. Meanwhile in the real world of UK home circumstances the NHS in England is heading for a £4 billion deficit and staff are haemorrhaging from the health service (110,000 vacancies that cannot be filled and growing at 9000 more every quarter) due to crap pay and conditions, ditto police, education… Read more »

Value for money. I second the call for another 5 at least please. Preferably an entire batch 2. Agincourt is a very much improved boat from Astute and compared to the French and American peers (not to mention Spanish debacle) these are real value for money.
They should be publically celebrated not complained about by people or groups with I suspect anti military or at best naive or partisan motives.
Look at the Typhoon £230m a pop (RAF figures not mine).
Getting good kit that works does not come free!

Julian

In what way is HMS Agincourt improved vs HMS Astute? Is it stuff that can be upgraded to the HMS Agincourt spec when HMS Astute comes in for a refit or is it more fundamental/invasive stuff than internal electronics refreshes and the like?

Ali
Guest
Ali

Astute, as lead boat in class is in just about everyway the prototype. Lessons learnt were applied to the following boats along with a few giant leaps forward in technology over the years. Some of the changes have been quite fundamental and the cost of a retrofit will reflect that.
From memory not so long ago there was quite rightly an attempt to pursuade the MoD to fund an eighth boat and keep Astute for trials and training.
We live in hope.

There is the vefy much delayed ordersfor the Astutes and there is significant American input… and the Pound has suffered recently.

BB85

I wonder how much of the increased cost is down to the slow build times requested by the MOD. There was a huge gap between boat 6 and boat 7 being ordered, so production was probably slowed even further on boat 6 to maintain jobs.
It is frustrating as the whole point is the costs go down and production speeds up as additional units are ordered. If they had not slowed things down to the extent they did, they may very well have got 8 boats for the price of 7 on the same delivery schedule.

So nothing in the Graphic shown for the T31?

Given the investment in technology would it not make sense to build some conventionally power subs and leverage the investment in sensors etc from Astute program?

T.S

Weak pound, high recent inflation, slow build rate and improved capability incrementally through the class. Simple, no shouting down bae required, maybe the government yes. But still huge value for money compared to others. Shrug shoulders and keep building as long the extra cost is fairly justified.

It’s easy to jump on the BAE bashing band wagon but the MOD and governments are primarily to blame with their on off will they won’t they approach to ordering.It was not long ago there were strong rumours that boat 7 was going to be cancelled ,these after all are very complex machines that require a very consistent ordering cycle to have any hope of controlling costs.Many of the sub systems themselves have a long lead time and need to maintain a strong skill base in their work force which still needs to be payed even if their doing nothing.

My eye caught the Type 26 line. On target for (going by eye) approx 1.8 billion budget.

Good point Chris. It does put things in a clearer perspective. So in essence Israeli defence is also funded by US foreign aid and they wouldn’t be a World leader in military development or capability without it.

Broadly agree with you, although I think the MOD needs to shoulder some of that responsibility too; my understanding is that they have been consistently unable to tell anyone where all the money has gone, on what. If I was the exchequer, or whoever hands out all the cash, I’d be very reluctant to give out any more until the recipient can prove what they’ve done with what they have already. The fact that they can’t show this would suggest a level of financial mismanagement too. With the current size of our military budget I honestly think we should be… Read more »

The ideal would be if we had a nuclear capable cruise missile capable of hitting Moscow from anywhere in the Atlantic. Suddenly our nuclear deterrent would change from a line hidden SSBN to every Astute and T26 – possibly T45’s too if they ever get those additional launch tubes. The Dreadnaught program could then be cancelled and the funds directed to even more Astutes. However as far as I’m aware no cruise missile has that capability, yet…

(Chris H) Sean – we had that capability until 1998 in the WE.177 nuclear bombs carried by most RAF and FAA aircraft. WE.177A was some 600Ib in weight, the B and C variants were 1000 Ib in weight. They could be delivered by torpedo or by launch from a ship as Nuclear Depth Charges against submarines or dropped from aircraft as wide ranging as Vulcan, Buccaneer, Harrier and were planned for TSR-2 and the P1154.

I would assume Paul they mean ( passive and active) detection and tracking of the other boat at advantageous ranges across various depths.

After all, modern homing torpedoes are extremely difficult to decoy, weapons like the upgraded spearfish will simply ignore noise makers and slam into the enemy.

Getting a firing solution first is what it’s all about..

“To hold a vessel at range” means that the submarine is able to detect the “enemy” vessel while remaining undetected itself; or are able to remain out of range of their weapons while they remain in range of yours. Without knowing the specific ground rules of that particular exercise, it’s difficult to totally interpret just what that comment means.
It should be noted that the exercise between the Astute and New Mexico occurred in 2012. Since that time the Virginia class subs have had a new block with totally redesigned and improved sonar arrays.

Nick Bowman

The only issue with Astute is weaponry. We’ve ignored significant advances in torpedo defence systems. The Russians have not. Will our Spearfish be effective forever? We need to at least contemplate new capabilities, even if the conclusion is that the existing weapons will be sufficient for the foreseeable future.

I have a vague memory of reading somewhere about improvements after the first 3, which would account for higher cost. It could be to do with longer term lessons learnt from Astute, not in time for 2 and 3. Memory, eh? A vague thing at times.

That’s the problem with presenting data in concise, bite-sized chunks. There often isn’t enough analysis and qualification accompanying it to know what it is really saying. If this increased cost is due to significant capability enhancements specified and implemented after boats 1 – 3 then extra capabilities do tend to cost extra money so it is not really any big deal (apart from having to be funded somehow) if we spent more vs the original budget to get more capability compared to the original specification vs these cost overruns being mostly down to badly negotiated contracts and/or politically-motivated interventions in… Read more »

The 823 million quoted is an accounting figure projecting inflation, depreciation, replacement of fixed assets and currency exchange costs going forward. The figure stands at 2018, By next year it could be more or less. The alternative would be to cancel a course that is not cost free and has very significant political and strategic risks.
