HMS Alliance — Attraction in Gosport

HMS Alliance is a Royal Navy A-class, Amphion-class or Acheron-class submarine, laid down towards the end of the Second World War and completed in 1947. The submarine is the only surviving example of the class, having been a memorial and museum ship since 1981. From 9 October 1947 until 8 November the submarine undertook a lengthy experimental cruise in the Atlantic Ocean off the coast of Africa to investigate the limits of the snort mast, remaining submerged for 30 days.

Between 1958 and 1960 Alliance was extensively modernised by having the deck gun and external torpedo tubes removed, the hull streamlined and the fin replaced with a larger (26 feet 6 inch high), more streamlined one constructed of aluminium. The purpose of these modifications was to make the submarine quieter and faster underwater. Following the modifications the wireless transmitting aerial was supported on a frame behind the fin; but was later replaced with a whip aerial on the starboard side of the fin which could be rotated hydraulically to a horizontal position.

The original gun access hatch was retained however, allowing Alliance to be equipped with a small calibre deck gun again when serving in the Far East during the Indonesian Confrontation of the earlier 1960s.

In May 1961 the pennant numbers of British submarines were changed so that all surviving submarines completed after the Second World War were now numbered from S01 upwards, and Alliance was given the number S67.

On 12 January 1968, she grounded on Bembridge Ledge off the Isle of Wight, but was subsequently refloated with the help of Admiralty tugs. On or around 30 September 1971 a fatal battery explosion occurred on board, whilst at Portlaoise

From 1973 until 1979 she was the static training boat at the shore establishment HMS Dolphin, replacing HMS Tabard in this role. In August 1979, she was towed to Vosper Ship Repairers Limited's yard at Southampton to have her keel strengthened so that she could be lifted out of the water and preserved as a memorial to those British submariners who have died in service. Since 1981 the submarine has been a museum ship, raised out of the water and on display at the Royal Navy Submarine Museum in Gosport.

Although listed as part of the National Historic Fleet, in recent years as many as 100 pigeons had been nesting in the submarine, causing extensive corrosive damage. She also sat on cradles over sea water, adding to problems of corrosion and preventing easy and economical maintenance to her exterior. Urgent repairs were needed and it was announced on 30 May 2011 that HMS Alliance would share in a £11 million Heritage Lottery Fund grant. Alliance would receive £3.4 million to repair her bow and stern and address extensive surface corrosion. The restoration included reclaiming land beneath HMS Alliance using a cofferdam and backfill. This provides easy access for future maintenance and a new viewing platform for visitors, additionally opening up the conning tower and casing. A new HMS Alliance gallery is also part of the project to help ensure visitors fully appreciate the significance of this submarine and what she represents.

Restoration was completed by March 2014, and the submarine was opened to visitors at the Royal Navy Submarine...

It is part of the Royal Navy Submarine Museum. It can only be visited as part of a guided tour. As a result, even if you have a ticket that includes all the museums in Gosport and the Historic Dockyards in Portsmouth, you still have to go to the museum ticket office for an appointment. The bad part is this is not written anywhere... and I found it out only after standing in line for about 10 minutes at the access stairs to the submarine, right after we got off the waterbus that brought us from Portsmouth. Anyway, I lost some time but I got over it. Access is done in relatively small groups, but, in my opinion, still a bit too big for how tight the place is. If you want to take pictures (as was my case) you have to stay a little behind the group, otherwise you won't be able to get an OK frame because of the crowding. The problem is that, in this case, you lose out on interesting explanations. In addition, you are also pressed by the next group, which comes from behind. Anyway, the visit is well worth it, it's very...

A truly unique attraction, HMS Alliance is a preserved World War II Royal Navy submarine, accesible with a guided tour. The tour guide, a former Royal Navy submariner, was hilarious, friendly and very knowledgeable. It is worth noting that there is no disabled access to the submarine, and conditions inside are extremely cramped. I would not recommend the (rather long) tour to those uncomfortable with confined spaces and loud noise.

If these things do not bother you, HMS Alliance provides a fascinating experience of the frankly horrible conditions endured by submariners during World War II. Tours are regular, and are booked from the museum's...
