Sandown Class Minehunter (RN)
Sandown Class Minehunter (RN)
^ HMS Bangor (M109)
The Sandown class is a class of fifteen minehunters built primarily for the Royal Navy by Vosper Thornycroft (now part of BAE). The Sandown class also serve with the Royal Saudi Navy and the Estonian Navy. The first vessel was commissioned into Royal Navy service on 9 June 1989 and all the British ships are named after coastal towns and cities. They have a secondary role as offshore patrol vessels.
These small (53 m) fibreglass vessels are single role mine hunters (SRMH) rather than minesweepers. Twelve ships were built for the Royal Navy and three ships were exported to Saudi Arabia. Three Royal Navy vessels were decommissioned following the Strategic Defence Review in 2003; Sandown (January 2005), Inverness (April 2005) and Bridport (July 2004). A further ship, Cromer, was decommissioned and transferred to a training role at the Britannia Royal Naval College in Dartmouth in 2001 as 'Hindostan'.
1. HMS Sandown (M101) Commissioned 1989. (Decommissioned 2005. Sold to Estonia in 2007, recommissioned as 'Admiral Cowan' (M313))
2. HMS Inverness (M102) Commissioned 1991. (Decommissioned 2005. Sold to Estonia in 2008, recommissioned as 'Sakala' (M314))

5. HMS Bridport (M105) Commissioned 1995. (Decommissioned 2004. Sold to Estonia in 2009m recommissioned as 'Ugandi' (M315))
6. HMS Penzance (M106) Commissioned 1998. (Decommissioned 2024. Awaiting fate.)
7. HMS Pembroke (M107) Commissioned 1998. (Decommissioned 2024. To be sold to Romania as 'Căpitan Constantin Dumitrescu' (M271))
8. HMS Grimsby (M108) Commissioned 1999. (Decommissioned 2022. Transferred to Ukraine, recommissioned in July 2023 as 'Chernihiv')
9. HMS Bangor (M109) Commissioned 1999. (In active serve, but damaged January 2024. Awaiting fate.)
10. HMS Ramsey (M110) Commissioned 2000. (Decommissioned 2021. To be sold to Romanian navy).

Re: Sandown Class Minehunter (RN)
Great news... does it mean, though, that the MH(P)C is going slower than expected, or for budgetary reasons has been kicked into the long grass?

MHPC is still happening, I don't think the focus is on building new ships for a while, especially since those new rivers are coming to fulfil the P part.ArmChairCivvy wrote:Great news... does it mean, though, that the MH(P)C is going slower than expected, or for budgetary reasons has been kicked into the long grass?
Hunts are good out until 2028, so it will be along time until we see the cheap multipurpose vessel we are expecting. Right now MHPC or MHC is going stong, 3 different development streams are active and working to develop the ofboard unmanned assets. These first be deployed on board the hunt class which may or may not be modified to better accept the new systems. Gabrielle has a nice ender of aa modified hunt but notes its old.
If all goes well aboard the humt then they will preceed to build a new mother ship, which will likley be a cheap steel support vessel, although a specialist composite hull has not yet been ruled out by the program.
So MHC is very active, but not looking to build new mother ships for 10 years or so .

Good news, there has not been mush released about the Sandown-class lately. I was fully prepared for them to be axed in the SDSR because of all the silence. Hopefully this break of silence and investment of funds committs the Sandown-class out until MHC takes over .

Re: Sandown Class Minehunter (RN)
The destroy once detected part is making good progress with the French SLAMF test bed
http://www.naval-technology.com/feature ... els-3.html
The Hunts basically are trialling stuff (for the overall concept) that are already in use in other navies. They got priority over Dandowns as 1. they have more space on the deck, and 2. the likeliest deployments in the near future will benefit from ability to self deploy (Sandowns being a tad small for that).
However, for the detection (or at least classification and identification steps, to decide on how to proceed) part you could seed an area, say a potential landing zone or a pinch point crucial for commercial shipping), with these little guys that are a fraction of the size of a sono buoy... maybe bigger, when they get all the necessary sensors:

Re: Sandown Class Minehunter (RN)
The SDSR says the mine hunter fleet will be cut from 15 to 12, presumably to free up resource's for the extra rivers. Trying to work out which class the cuts will come from is something of a mystery
The hunts are much older but have had new sonar and new engines recently, and as mentioned above, have a greater potential to become a kind of interim MHPC ship.
The sandown class is pretty new, but smaller than the hunts and is just starting an upgrade to its sonar for all the ships in the class.
So to me there their is no indication where the cuts will come from. It seems the navy planned to support all 15 in the long term, with upgrade contract's being awarded in September, it appears the decision to cut the fleet came late when they realised they would have to support extra rivers.
Any thoughts/news and which ships will go ?

Re: Sandown Class Minehunter (RN)
It might just be that a buyer was found (late in the day).
If that theory is proven correct, then I would say the Sandowns are more in demand. From the UK point of view their minuses are
- too small to easily self deploy to the most likely scenes of action
- limited deck space, to support the transition to off-board systems
For a littoral navy with no modern capacity they would be absolutely fine

Mrs Madeleine Moon
To ask the Secretary of State for Defence, whether (a) HMS Brocklesby M33 mine sweeper will be refitted at Portsmouth naval dockyards and (b) that refitting will include new propulsion capability; and if he will make a statement.
Might just be until more money is allocated next year, or could be an indication that Brocklesby will be one of the MCM vessels that will be decommissioned.Mr Philip Dunne
As part of the Royal Navy’s continual examination of its resources and operational priorities, HMS Brocklesby’s docking period and refitting of her propulsion capability has been deferred.
Re: Sandown Class Minehunter (RN)
Or perhaps it'll be the first Hunt to be refitted with the open mission space in the back and the A frame for putting the unmanned boats in the water. The Royal Navy has been trying to obtain the conversion of a Hunt for a few years now. It was already planned as part of the old FAST demonstrator adventure...

SDSR Factsheet published by government confirms that 3 Sandown of the oldest ones will pay off by 2025 to go down to 12 MCM ships.

Re: Sandown Class Minehunter (RN)
So it does
The correct choice, and unusual the older ship is the one with the bigger margin for growth this time.
Will leave an odd little fleet of 4 sandowns at the end. The 2025 dates does seem a long way off though, not long before the rest will be gone to make way for HMC a few years later.

Re: Sandown Class Minehunter (RN)
Funny things the Sandowns, extremely expensive for their size and limited in their role. Can't help but feel we could've got a lot more bang for our buck had we built a modernised "Hunt II" instead.

Let's put that in perspective:Engaging Strategy wrote:Funny things the Sandowns, extremely expensive for their size and limited in their role. Can't help but feel we could've got a lot more bang for our buck had we built a modernised "Hunt II" instead.
- Hunts were sweepers
- the nxt-gen (then) was mine hunting, along came the Sandowns
- 3rd gen is still mine hunting, but this time with off-board systems
... still being proved; and the Hunts with their bigger decks can accommodate the transition and trials
Not everyone (hardly anybody) are on the third wave yet; hence (as Mark says) there is a market for Sandowns

Re: Sandown Class Minehunter (RN)
Cannot these "4" Sandowns be replace with "4" River B.1s, with plenty of space in their stern...?shark bait wrote:Will leave an odd little fleet of 4 sandowns at the end.
my self-answer is, "Maybe no".
It will cost "huge" to equip River B.1s with UUV/USV based MCM assets. Because River B.1 is purely an OPV, only a "vessel", no CMS no good com-link and no hi-level navigation.
sorry, turned out to be just talking myself....

Re: Sandown Class Minehunter (RN)
I think the sandows are going so we can man the new river's. There is no way the navy could increase hull numbers, so something had to give.
This leaves no crew for the B1 rivers so it does seem higly unlikely they could be used for MCM. If we did need to replace the sandows, perhaps the echos could be used.
The echos could be useful for picking up some MCM work, they already come with boat launching facilities, and could be a good platform to develop off board MCM. Echos are clearly not busy surveying at the moment

Re: Sandown Class Minehunter (RN)
Now being the operative word... or rather, when Ocean and the 3 Sandowns go. Very tight. We might see a few OPVs tied up and waiting for a buyer... just like what happened with the corvettes for Brunei (for how many years was that - before BAE got some German company as a middleman to sell them).shark bait wrote: I believe they have allowances to be properly crewed now.

Re: Sandown Class Minehunter (RN)
I Don't think anything shall be tied up waiting for a buyer, although an Albion will remain tied up. I especially dont think we will see the rivers tide up. Replacing Sandowns for new rivers, plus the 1st sea lords comments, suggest they plan to operate all of the new more capable rivers, and deploy them abroad more.
Man power will of course be tight, but I think it is feasible, leadership will need to be a little creative and particularly efficient though.
Available resources will soon look something like this;

- 300 coming from ocean, plus embarked aircraft operators
- 400 extra from the SDSR
- 300 extra coming from the plan to swap 300 officers for 600 ratings.
- 358 were required for these classes pre SDSR
- 316 are now required post SDSR (280 if Clyde also goes)

Good stuff, just a couple of comments/ questions:shark bait wrote:operate all of the new more capable rivers, and deploy them abroad more. (A)

300 extra coming from the plan to swap 300 officers for 600 ratings
A. I meant the old Rivers (why would you otherwise buy something that has been on an operating lease, and start to own it outright when it/ they are nearing the end of their (RN) life?)
B. Would that be Topmast and longer tours? Anything else?
C. From what I read, at the time, in the bolded part there might be some double counting... would it be more like a package, with 400+300, rather than what you have done, taken a cost line and translated it into cheaper units?
- there may have been sources on this that I have missed, just checking

Re: Sandown Class Minehunter (RN)
(A) That makes sense then. They have a few years to find a buyer. I guess it was never the plan to replace them so soon otherwise they would never have bough out the lease.
(B) I don't really know, it will be tight though.
(C) I hoped there wold be some discussion on this part, again I am unsure. There has been a plan for a while now to swap 300 officers into 600 ratings.
Post SDSR I don't know weather that plan has been superseded by, included in, or on top of, the 400 extra sailors stated in the SDSR.
This link seems to suggest it on top of the extras from the SDSR
http://www.savetheroyalnavy.org/the-state-of-the-rn/
can anyone clarify?

the hunts were always muliti role mine hunters. they were equipped to both hunt and sweep. unlike the sandowns who were single role mine hunters.

Re: Sandown Class Minehunter (RN)
that's probably right, now sweeping has been officially discontinued so they are both hunters, but the Hunts better at self-deploying and fitting in all the offboard stuff (both on the small side for remote boat ops)
