 Upholder
Upholder had no luck at all on her next four patrols and she wasted a number of extremely valuable torpedoes - very scarce in Malta, whose supply convoys were not worth a torpedo, by the Germans and Italians.
Upholder's fortunes changed sharply for the better on her sixth patrol when Wanklyn sent the Antonietta Laura (5,428 tons) to the bottom, finished off a German merchantman which had been abandoned on a shoal and sank two vessels from a heavily escorted convoy, eluding the escorts despite weather conditions which markedly favoured the enemy.
Upholder stopped every piece of machinery that she could; her crew froze in utter silence, knowing that the slightest noise would bring instant retribution from the destroyers hunting overhead.

Submarines are also used for marine science and for work at depths too great for human divers.
Submarines are useful to a military because they can approach their attack victim without necessarily being detected, then strike at close range.
The first military submarine was the Turtle, a hand-powered spherical contraption designed by American David Bushnell that accommodated a single man. During the American Revolutionary War in 1776, the Turtle attempted and failed to sink a British warship, the HMS Eagle in New York harbor.

Upholder had obtained her first score on her first patrol when she hit or damaged an 8000-ton supply ship and on 25 April 41 she sank the 5428-ton Antonietta Lauro.
It was carried out in failing light and was made at periscope depth throughout, the Upholder's listening gear being out of action and thus preventing her from going deep and closing the convoy by steering towards the sounds of propellers.
As the Upholder fired her torpedoes, she went deep in an effort to evade the inevitable counter-attack from the destroyers.

It was originally envisaged that with a building rate of one per year the Upholder Class could consist of as many as 19 boats, with later vessels forming an improved second and third batch.
The Upholder Class were the first conventionally powered submarines to be built with a 'teardrop' hull.
During their short service in the Royal Navy, the Upholder Class became the last submarines to be based at HMS Dolphin as part of the 1st Submarine Squadron.

 Upholder Class Overseas Patrol Submarines
However conventional submarines still had a role in the post war era: being smaller and quieter they were more suited to work in coastal or shallow waters as required for 'cloak and dagger' operations.
Further resemblances to nuclear submarines included anechoic (noise reducing) tiles on the hull which muffle internal noise and reduce sonar returns, while the fin was constructed from glass fibre in order to be as lightweight as possible.
During their short service in the Royal Navy, the Upholder Class became the last submarines to be based at HMS Dolphin Gosport as part of the 1st Submarine Squadron.

 Navy League of the United States - Citizens in Support of the Sea Services
Built by the Australia Submarine Corporation (ASC), all six Collins-class submarines were delivered at a final cost of approximately $3.4 billion, in essence more than $500 million per unit, considerably higher than the cost of the average diesel-electric submarine available on the international market.
Most of the additional costs are associated with infrastructure improvements at ASC and training for submarine construction, as well as repairs and upgrades that are usually associated with a country that attempts to build a complex system for the first time.
The Provincien class is the first to operate the APAR multifunction radar--developed by Thales Naval Nederland--which is integrated with the Raytheon long-range SM-2 Standard missile, and may be integrated as well in the future for the Evolved SeaSparrow Missile (ESSM) and Theater Ballistic-Missile Defense (TBMD).

 Reference.com/Encyclopedia/Upholder/Victoria class submarine
The Upholder/Victoria-class submarines also known as the Type 2400 (due to their displacement of 2,400t) are diesel-electric hunter-killer (SSK) submarines designed in the UK in the late 1970s to supplement the Royal Navy's nuclear submarine force.
The submarines are packed with technology generally found only on nuclear-power submarines and are still widely regarded as being among the best diesel-electric submarines in the world.
They are essentially identical to modern nuclear submarines (with the distinctive nuclear shape and sonar-absorbing tiles) but run on diesel engines instead of nuclear reactors (which limits their range, but conversely makes them quieter and more manoeuvrable).

These submarines were decommissioned from the Royal Navy in 1993 and were then laid up for several years, after the Royal Navy decided to focus solely on nuclear submarines as a cost-saving measure.
These submarines are twenty-five years more modern than the OBERON class submarines that they replace, and they represent a substantial leap in techology over their predecessors.
This class of subs is suffering a large number of teething problems on being reactivated, possibly exacerbated by the long period of deactivation.

The submarines have been employed in an anti-submarine role, training of the surface fleet of Canada and her allies, and in aid of other government departments — fisheries patrols for the Department of Fisheries and Oceans (DFO) and drug interdiction operations for the RCMP.
She felt the government should not be spending money on submarines while at the same time slashing billions of dollars in provincial transfers and that the money would be better spent on quality of life in the military.
Submarines have also assisted the RCMP in combating drug smuggling in Canadian waters, in 1994 an O-boat made a significant contribution in a large-scale drug interdiction operation.

 Pursuing the upholder option Sea Power - Find Articles   (Site not responding. Last check: 2007-10-10)
New Canadian submarines must be very quiet and have small crews, a low indiscretion ratio, excellent sensors, first-class tactical dataprocessing equipment, and torpedo tubes (preferably six) compatible with the Mark 48 torpedoes already carried by the aging "O boats" (Oberon-class submarines).
The 209 class (by reputation the most popular export submarine in the world) is unsuitable, being too small; the TR1700 could be a strong contender because it is proven, the right size, and operates with a crew of 29; the boats of a new class, the 212, will have AIP (air-independent propulsion) but are unproven.
A modern diesel/electric patrol submarine designed for the rigors of operating in the northern oceans, the Upholder is well-proven in all the roles Canada requires.

The third submarine of the class, the Weller, was commissioned on 10 July; the fifth, the Sheean, was launched on 1 May, and the sixth and final submarine, the Rankin, is to be launched this May. The Sheean and the fourth submarine, the Dechaineux, are to be given an interim--but expensive--upgrade before entering active service.
The submarine Michishio, second unit of the 3,600-ton Oyashio class, was commissioned on 10 March; the fourth, the Makishio, launched on 22 September; and the sixth was laid down on 2 April--out of a planned total of ten that will maintain the conventional submarine fleet at 16 very modern units.
The submarines are to be delivered in 2004 through 2007, while the 3,590-ton frigates, nearly eight times the size of the largest surface combatants now in South African service, are to enter service in 2004-2005 after several years of training and workup.

that the Upholder Class was not considered to be the least of the bunch.
Teams of Canadian experts were involved in assessing the submarines before the deal was struck, and they have been involved in the reactivation and the acceptance.
The Victoria class is among the best of diesel-electric subs, but the limitations of their powerplant make them impractical for a country with a coastline and climate like ours.

It is seldom proper for their Lordships to draw distinction between different services rendered in the course of Naval duty, but they take this opportunity of singling out those of Upholder under the Command of Lieutenant Commander Wanklyn for special mention.
She was long employed against enemy communications in the Central Mediterranean, and she became known for the uniformly high quality of her services in that arduous and dangerous duty.

 'Upholder' submarines
The Upholders' Company established a link with the first HMS 'Upholder' (1940-1942) during the second World War when the Worshipful Company adopted the submarine and sent the Ship's Company books, food parcels and many other comforts which, we believe, helped to relieve the austere conditions aboard a wartime submarine at that time.
The second submarine named 'Upholder' was built by VSEL for the Royal Navy and launched by Her Royal Highness the Duchess of Kent on 2nd December 1986.
The new 'Upholder Class' was, unfortunately, not to stay in service for many years and HMS Upholder was de-Commissioned at the end of April 1994.

On 12 April 1942 HMS Upholder was ordered to form a patrol line with HMS Urge and HMS Thrasher to intercept a convoy.
It is not known if this signal was received and the submarine failed to return to harbour on her due date.
Despite British claims that Upholder should have been far away, there is no sub reporting this attack, the contact was definite and sharp and there is reasonable certainty of a sinking or severe damage, therefore it is believed this attack accounted for Upholder's demise.

The need for a new class of conventional submarine to replace the ageing Oberon class was made public in 1979, when the Type 2400 design was revealed.
The initial requirement for twelve boats was cut to ten, and then the 1990 - 91 Defence Review cut the class to four.
By this time, the Cold War was over, and their recon role was no longer needed, and in the hard financial climate of the day, it was decided that the Submarine Branch should be all nuclear.

 How Safe Are Our Subs?
No such incident has ever occurred in a Collins Class submarine and it seems likely that the Senator was confusing the incident with such an event which did occur on board a British Upholder Class submarine during builders trials in the late 1980's.
The answer lies in the RAN Submarine Safety Program (SUBSAFE) that was specifically developed within the New Submarine Project as part of the process of bringing the Collins Class submarines into service.
Combat Survivability: Addresses the submarine's design and its ability to withstand underwater explosive shock and torpedo impact, the use of redundancy to maintain services affected by damage and other areas that might affect the ability to fight the submarine, such as crew training, flooding, fire fighting and toxic gas management and control.
