Offensichtlich ist das Midlife Update des Spearfish noch nicht so weit gediehen, das die DPA (Defence Procurement Agency) des MOD dies für veröffentlichbar hält:

WASS's heavyweight Black Shark torpedo already has been ordered by the Chilean Navy for its new submarines.

An exerpt from Janes on the A184/Blackshark
------------------------------------------
In the late 1980s, the A184 was trialled for the US Navy's low-cost Anti-Surface Warfare Torpedo (ASuWT) programme. Although the trials were successfully concluded, the US Navy decided not to proceed with the programme.
In 1998, WASS revealed it was developing an upgraded version of A184 for the Italian Navy with the objectives of improving passive and active acquisition ranges by factors of 300 and 200 per cent respectively, increasing speed by 150 per cent and endurance by 200 per cent. The weapon was originally designated A184 Advanced, although by February 1999 this weapon had been renamed Black Shark. This weapon features a new seeker, which has been under test since the summer of 1998, and which was selected by Chile for its new 'Scorpene' class submarines which are scheduled to enter service in 2004. Sea trials of the weapon are scheduled for 2003 and submarine launches in the following year.
At Euronaval 2000, WASS and France's DCN International announced they would combine development, production and marketing of a new heavyweight torpedo based upon Black Shark having signed an industrial co-operative agreement in July 2000. This has received the provisional designation Black Shark/IF 21 (Italy-France, 21st Century). Sub-systems have been tested since 2000 and a complete prototype is scheduled to begin tests in 2003 with production beginning in 2004.
Description
The A184 is a dual-purpose (surface vessels and submarines) torpedo which, externally, is a long slim cylinder with rounded nose, four rectangular fins and exposed contra-rotating propellers.
Internally, the digital SEPA AG 67 active and passive mode seeker is in the nose. This has two semi-circular electro-acoustic transducer arrays, one vertical and the other horizontal. The Alenia guidance unit calculates the target's exact location. Behind it is the 250 kg HBX warhead with magnetic influence and impact fuzes. The centre of the torpedo contains the silver-zinc oxide batteries. The rear third of the weapon contains the electronic guidance package, the gyroscope and guidance wire dispenser and the 93 kW electric contra-rotating motor driving skewed direct-drive propellers with seven and six blades. The weapon is capable of two speeds: 24 and 36 kt.
The A184 may be launched from swim-out or water-pulse submarine torpedo tubes and it may also be launched from the B 516 torpedo tubes (See B 515/ILAS 3 and B 516 entry in Weapon Handling and Launching Systems section).
Commands carried by the guidance wires include: course, depth, acoustic mode (active, passive and combined), enabling range, stratum allowed, speed, impact and influence fuze setting and torpedo stop. Replies from the weapon include: course, distance, depth, acoustic mode, speed and other data on interrogation. The fire-control system displays the tactical scenario, acquiring data from onboard sensors and allows the underwater weapon selection, check presetting, start and guidance against the designated targets. The fire-control system is modular, each module capable of being used independently in case of failure in the others.
The latest production version is Mod 3 with the improved torpedo sonar (TOSO) which incorporates the Intel 486 processor to permit operations in a multi-target situation with strong reverberation environment and despite the use of counter-measures. TOSO, which operates in the 30 kHz range, also provides the Mod 3 with both a wake-homing and a re-attack capability.
DCN and WASS are developing Black Shark (formerly A184 Advanced) with the Astra seeker and fibre-optic wire guidance. The new ASTRA (Advanced Sonar Transmitting and Receiving Architecture) seeker features a flat planar array and for longer ranges can operate at 15 kHz. Signal and data processing will include spatial and frequency filtering, echo elongation, angular extension and spatial coherence analysis together with DEMON analysis. These parts and the afterbody will be produced by WASS. The brushless drive motor will permit speed changes in 1 kt increments and will provide a higher maximum speed. improved range and less radiated noise, power being provided by Aluminium-Silver Oxide batteries, exploiting technology of the MU 90 Impact (qv). French sources suggest that lithium-ion module batteries might be considered for future torpedo programmes which might include IF 21. The motor section together with warhead and fuze system will be produced by DCN.
At the Underwater Defence Technology conference in Hamburg in June 2001, Whitehead representatives suggested that heavyweight torpedoes could be used to extend sensor ranges but this would require better, lower speed control. They suggested this might be achieved by adapting the vertical control surfaces and improving the control software. This too might also be applied to IF 21.
Some 500 A184 torpedoes have been produced and the weapon is still being marketed but it is in service with only two customers. Export sales of the weapon probably total about 100 weapons with an estimated Italian requirement for about 100. In late 2002 the manufacturers were offering the weapon to the French and Greek. Peru ordered A184 torpedoes but the contract encountered problems and none were delivered.

Chile's two new Scorpène-class attack submarines, O'Higgins, shown here on sea trials in September 2004, and sister Carrera, will be the first foreign warships to be armed with the new Black Shark dual-purpose wire-guided heavy torpedo. Torpedo trials on the O'Higgins were conducted in November 2004.

The O’Higgins, the first Scorpene submarine for the Chilean Navy, passed a major test programme milestone on 20 November 2004 by firing two torpedoes while running at depth off Lorient, France. The standard production weapons were one SUT torpedo and one Black Shark torpedo. The tests demonstrate that the Scorpene design can indeed deploy and guide different types and generations of torpedoes.
Der BAe Spearfish hat eine Geschwindigkeit von 65kn und 60km Reichweiteund ist auf der HMS Vanguard bereits im Einsatz was zumindestens mehr ist als was die öffentlich zugänglichen Seiten für den Balck Shark hergeben. Trotzdem ein sehr guter Torpedo!:daumen:
