HMS Dreadnought (1960–1964) |
(28 kts / ~6 kts) • US: Slower sprint. Skipjack hits ~30 kts. • USSR: Slower sprint. November hits ~30 kts. • France: Lacks SSNs. (Outpaces French diesel Narval’s 18-knot sprint). |
(~135 / >165 dB) • US: Par with Skipjack (both use noisy S5W steam plant). • USSR: Quieter than November (which lacked isolation). • France: French diesels are quieter on battery. |
Mk 8 Mod 4 / Mk 20S Bidder / Mk 23 Grog (6 Bow Tubes) • US (Skipjack): 6 Bow Tubes. The Mk 23 Grog (20 kts) equalizes the tactical gap with the US Mk 37 (26 kts, active sonar); the Grog’s wire-guidance allows you to manually steer past decoys or hit silent targets, offsetting the US active-ping advantage. • USSR (November): 8 Bow Tubes. Soviet SET-53 (29 kts, passive acoustic, 287 kg) is faster than Bidder/Grog, but British Mk 8 (45 kts, 365 kg) has vastly superior unguided kinetic punch. • France (Narval Diesel): 6 Bow + 2 Stern Tubes. French L3/E14 (25 kts, active/passive, 200 kg) are faster than Grog, but lack wire-guidance. |
Type 2001 Bow Array: • US: Par with Skipjack (BQS-4). • USSR: Better than November (Arktika-M). |
Awkward Handling: Married a British whale-like forward hull to an American rear; handles worse and has a larger turning circle than the pure teardrop US Skipjack. Low Countermeasures: Relies purely on evasive maneuvers; no dedicated automated torpedo decoys. |
HMS Valiant / Churchill (1966–1973) |
(28 kts / ~8 kts) • US: Faster sprint. Sturgeon tops out around 26 kts. Silent speed is par (~8 kts). • USSR: Vastly slower sprint. Victor I hits 32 kts; Alfa hits 41 kts. • France: Lacks SSNs. |
(~125 / ~158 dB) • US: Par with Sturgeon (Both introduced machinery rafting). • USSR: Vastly superior to Victor I and the screamingly loud Alfa. • France: Diesels are quieter on battery. |
Tigerfish Mod 0 / Mk 8 (6 Bow Tubes) • US (Sturgeon): 4 Amidships/Angled Tubes. US Mk 48 (55 kts, wire/active) makes the Tigerfish (35 kts, wire/active) obsolete in closing speed. However, the UK 6-tube forward volley is easier to aim than the angled US layout. • USSR (Victor I/Alfa): 6 Bow Tubes. Soviet 53-65K (45 kts, wake-homing, 308 kg) creates an undodgeable surface-ship threat the UK lacks. • France (Agosta Diesel): 4 Bow Tubes. French L5 (35 kts, active/passive, 150 kg) matches Tigerfish speed but lacks wire-guidance precision. |
Type 2001 + Type 2007 Flank Array: • US: Sturgeon bow sphere is better, but Valiant flank arrays beat US side hydrophones. • USSR: Far superior to Victor/Alfa. |
Deep-Diver Meta: Built from high-tensile steel with high test-depth ratings. In WT, you can dive below thermal layers faster to break enemy sonar locks or evade shallow-set depth charges better than early Soviet SSNs. |
HMS Churchill (1979 Pump-Jet Trial) |
(28 kts / ~14 kts) • US/USSR: Sprint is par/slightly worse. However, Silent Speed is superior. The pump-jet allows 14 kts silent while US/USSR cavitate heavily above 8–10 kts. |
(~118 / ~148 dB) • US/USSR/France: Superior intermediate stealth to ALL contemporaries. The pump-jet delays cavitation, remaining as quiet as a Sturgeon at 8 knots. |
Tigerfish Mod 1 (6 Bow Tubes) • (Identical torpedo kinematic capability gap as base Valiant). |
Type 2001 + Type 2007 Flank Array: • (Sensor capability identical to Valiant, but lower self-flow noise improves high-speed listening). |
Superior Acceleration: The pump-jet propulsor provides immense low-end torque. In WT, this allows for rapid “crash-starts” to dodge incoming torpedoes better than standard skewed-screw contemporaries. |
HMS Swiftsure (1973–1981) |
(30 kts / ~10 kts) • US: Slower sprint. 688 hits 32–33 kts; silent speeds are par. • USSR: Par sprint with Victor III (31 kts); British silent speed is superior (10 kts vs 8 kts). • France: Vastly faster sprint. French Rubis maxes out at 25 kts. |
(~115 / ~145 dB) • US: Slightly quieter than early 688 Flight I. • USSR: Much quieter than Victor III. • France: Outclasses the French Rubis, which is loud for its size at sprint. |
Tigerfish Mod 2 / Harpoon (5 Angled Bow Tubes) • US (688 Flight I): 4 Amidships/Angled Tubes. Mk 48 (55 kts) remains critically faster than Tigerfish (35 kts). • USSR (Victor III): 6 Bow Tubes. Soviet TEST-71 (40 kts, wire-guided) outperforms Tigerfish speed, while the 65-76 Kit (50 kts, wake-homing, 557 kg) massively outclasses UK surface lethality. • France (Rubis): 4 Bow Tubes. French F17 (40 kts, wire-guided, 250 kg) is slightly faster than Tigerfish with identical guidance mechanics. |
Type 2020 Bow + 2046 Towed Array: • US: Par with 688 (BQQ-5). • USSR: Better than Victor III. • France: Vastly superior to Rubis (which lacks hull space for large arrays). |
The Dogfighter: Extremely compact, “fat” hull design giving it a phenomenal turning circle compared to the US 688 (which handles like a bus). Weakness: Smaller magazine capacity; you will run out of torpedoes faster in WT Enduring Confrontation than US/USSR equivalents. |
HMS Trafalgar (Early) (1983–1988, Skewed Screw) |
(31 kts / ~10 kts) • US: Slower sprint. 688i matches silent run but reaches 32+ kts sprint. • USSR: Slower sprint. Akula I reaches 33 kts. • France: Vastly faster sprint than Améthyste (25 kts). |
(~110 / ~142 dB) • US: Matches 688 Flight I/II. • USSR: Quieter than Akula I. • France: Superior to the Améthyste refit. |
Tigerfish Mod 2 (5 Angled Bow Tubes) • US (688 Flight II): 4 Amidships/Angled Tubes. Critically outpaced by American Mk 48 ADCAP (60 kts). • USSR (Akula I): 8 Bow Tubes (4x 533mm, 4x 650mm). Outpaced by Russian USET-80 (48 kts, active/passive/wake). • France (Améthyste): 4 Bow Tubes. Par with French F17 Mod 2 (40 kts, wire-guided). |
Type 2020 + 2046 Clip-on Array: • US: Matches 688 Flight II. • USSR: Better low-frequency sorting than Akula I. • France: Superior to Améthyste. |
Submarine Flares: Standardized 2x SSE Mk8 launchers for Type 2066/2071 acoustic decoys. Acts like aircraft flares against incoming active torpedoes. High Survivability: Anechoic tiles could act as a buffer against kinetic warhead overpressure in the WT damage model? |
HMS Trafalgar (Late) (1989–1991, Pump-Jet) |
(32 kts / ~15 kts) • US: Slower overall than Seawolf (35 kts / 20 kts silent). Par sprint with 688i, but pump-jet gives vastly superior silent speed. • USSR: Slower sprint than Akula II (33 kts), but much faster silent speed. • France: Outclasses Améthyste in all speed metrics. |
(~105 / ~136 dB) • US: Par with 688i / Seawolf at slow speeds; pump-jet is superior at intermediate sprint. • USSR: Par with Akula II (Vepr) at low speeds. • France: Quieter than Améthyste. |
Spearfish (80 knots) (5 Angled Bow Tubes) • US (688i / Seawolf): 688i (4 Amidships); Seawolf (8 Amidships 660mm). Spearfish (80 kts) completely outclasses the Mk 48 ADCAP (60 kts) in raw closing velocity. • USSR (Akula II): 8 Bow Tubes. Spearfish is drastically faster than Russian USET-80 (48 kts). • France (Améthyste): 4 Bow Tubes. Spearfish doubles the speed of French F17 Mod 2 (40 kts). |
Early Sonar 2076: • US: Matches 688i, slightly behind Seawolf sphere. • USSR: Superior flank resolution to Akula II. • France: Far superior to Améthyste. |
Apex Ambush Profile: High-speed pump-jet acceleration + acoustic decoys + 80-knot Spearfish. You can pop flares to defeat an incoming Russian USET-80, crash-accelerate away, and fire an undodgeable 80-knot return shot. |
HMS Astute (2010–Present) |
(30 kts / ~16 kts) • US: Seawolf is still kinetic king (35 kts / 20 kts silent). Astute edges Virginia in silent speed, par in sprint. • USSR: Par with Yasen-M sprint (31 kts); Astute has faster silent speed. • France: Vastly faster sprint than Suffren (25 kts); par silent speed. |
(<95 / ~128 dB) • US: Matches/exceeds Virginia. • USSR: Quieter than Yasen-M. • France: Par with / slightly quieter than Suffren. |
Spearfish Mod 1 (6 Bow Tubes) • US (Virginia): 4 Amidships Tubes. Spearfish (80 kts, fiber-optic) is faster than Mk 48 Mod 7 (60+ kts), though US matches it in shallow-water ECCM. • Russia (Yasen-M): 10 Amidships Tubes. Spearfish dominates Russian Fizik (50 kts, fiber-optic) in speed. • France (Suffren): 4 Bow Tubes. Faster than French F21 (50 kts, fiber-optic). |
Full Sonar 2076 Suite: • US: Rivals/exceeds Virginia; superior to Seawolf. • USSR: Far superior to Yasen-M. • France: Superior to Suffren. |
The Arsenal Ship: Massive 38-weapon internal magazine layout. You can spam torpedo salvos into cap-zones indefinitely, whereas the US Virginia has a very small internal torpedo room (heavily reliant on VLS tubes which WT won’t use in sub-vs-sub). |
