FACTS & TRIVIA #1: Modern torpedo launchers, USS Hull, HMS Victoria, Mississippi class and HMS Vanguard

Written by D-Mitch

This is the first of a new category of articles where all the significant and interesting facts in naval history as well as "strange" and unique features of naval combattants' equipment, will be described in brief. Enjoy the first part of my collection!

1. Non-trainable torpedo launchers in unusual positions on modern surface combatants

There are various torpedo launchers on modern large warships; some of them are trainable such as the popular US Mk32 triple/twin torpedo launcher, the B515 (ILAS-3) and the Russian ChTA-53, and some are not such as the US Mk32 Mod 9 twin launcher or the Cray Marine twin launcher. What do all these launchers have in common? They are located mainly amidships on large warships and on small vessels across the deck (Pauk class, torpedo craft etc.) or at the stern in a two-single torpedo launchers configuration (Combattante class etc.). But there are some large warships in modern era that had/have torpedo launchers in quite unusual positions and configuration. Such ships are the following:
  • Hamburg class destroyers and Deutschland training cruiser of the German Navy

Deutschland's twin stern launcher
During the '50s, Germany began building her Navy. Some of the first major surface combatants that entered service with the post WWII German Navy were  the four (4) Hamburg class destroyers (1964 - 1994) and the training  cruiser Deutschland (A59) (1966 - 1990). The Deutschland was constructed and used as a training cruiser in peacetime and planned for multi-role missions in the event of war: troop ship, hospital ship, minelayer, and escort vessel. These five large vessels had something unique for warships of that era. Like the old battleships, had non-trainable torpedo launchers located at the bow and the stern (not the Deutschland). The Hamburg class destroyers had a triple launcher at the bow and a twin at the stern while Deutschland except the trainable 533 mm ASW torpedo tubes, they had also two fixed 533 mm torpedo tubes aft at the stern. These launchers were later removed from all the ships mid-1970s and both the stern and bow were redesigned.

  • Maestrale class frigates of the Italian Navy

The eight (8) Maestrale class frigates (1982 - present) of the Italian Navy were primarily designed for anti-submarine warfare (ASW). Therefore, except the two 324 mm ILAS-3 triple torpedo launchers they were equipped initially with two Whitehead B-516 21in (533mm) non-trainable torpedo launchers at the stern below the helicopter hangar, for Whitehead A-184 heavyweight torpedoes. These launchers and the torpedoes were later removed as they were considered inadequate.

  • Neustrashimy class (Project 11540) frigates of the Russian Navy

There are two ships in the class, the Neustrashimy (commissioned 1993) and her much younger sister Yaroslav Mudry (commissioned 2009). As usually, the Russian warships carry an impressive armament for their size but these vessels have something unique hidden in the superstructure. Six 533mm torpedo launchers, mounted in the superstructure, are capable of firing Starfish (RPK-2 Vyuga, known also as SS-N-15) or Stallion (RPK-6 Vodopad/RPK-7 Veter, known also as SS-N-16) ASW missiles or Type 53 ASW/ASuW torpedoes. The Starfish missile has a maximum range of up 45 km while its payload is either a simple depth charge or a 200 kt nuclear warhead! The Stallion missiles are dual-role; they can be armed with either a 400 mm anti-submarine torpedo or a nuclear depth charge in a range of approximately 100 kilometers, an impressive boost over its predecessor the SS-N-15 Starfish. Watch how this impressive system work in this video. So the next time you spotted Neustrashimy without her anti-ship missile launchers (only Mudry has them till today), you will know that the ship is not unarmed but it carries a hidden deadly weapon system mounted in the superstructure.

  • Al Riyadh class frigates of the Royal Saudi Navy

The three Al Riyadh-class stealth frigates (commissioned in 2002) of the Royal Saudi Navy, are the most modern warships today that are armed  with non-trainable torpedo launchers at the stern. The frigates of the class are an expanded anti-aircraft warfare version of the French La Fayette class frigates, displacing about 4,700 tonnes and extended to 133m in length. They are armed The ships are armed with four (!) 533mm (21.0 in) aft torpedo tubes for DCNS F17 heavyweight anti-submarine torpedoes.

2. The last 8in gun developed for the US Navy

The USS Hull (DD-945), was a Forrest Sherman class destroyer that during her major overhaul in 1974-75, her forward 5 in./54 Mark 42 gun mount was replaced with an 8 in./55 Mark 71 gun mount. This Major Caliber Lightweight Gun ("MCLWG") was the result of a project dating back to the 1960s, when it was realized that heavy gunfire support for amphibious operations would die with the existing force of heavy cruisers unless a big gun could be developed for destroyer-size ships. Hull was its test ship for seagoing trials, after which it was expected that several of these guns would be installed on board destroyers of the new Spruance class. The firing tests were reportedly partially successful. Unfortunately, when the gun was fired as far to the rear as possible, the shock was too great and some strakes were broken. The MCLWG project was cancelled in 1978. This was the last 8in gun developed for the US Navy and USS Hull was the only modern destroyer to carry such a heavy gun. Someone could notice that the Mk55 gun turret resembles a lot to the modern Mk45 5in gun turret. The introduction into service of the USS Zumwalt destroyer with her 6.1 in guns, makes it the largest caliber gun today in US service and in the world together with the Peruvian cruiser Almirante Grau.

3. The largest wooden warship which ever entered service

ΗΜS Victoria last of Royal Navy ship of the line
The 121-gun HMS Victoria was the last wooden three-decked ship of the line built (first rate) for the Royal Navy. With a displacement nearing 7,000 tonnes and an overall length of 79.2 meters, she was at the same time the largest wooden warship which ever entered service.She was armed with a total of 121 guns. Read more about the ship and other large ships of that era here.

4. The only US Navy battleships to fly a foreign flag

The two Mississippi class battleships were the only US Navy battleships to pass out of American service and to fly a foreign flag! Idaho and Mississippi were two pre-Dreadnoughts of 14,500tons displacement at full load and of 116m length while they were armed with four 12in, eight 8in and eight 7in guns. Greece purchased the two vessels from the USA in 1914; Idaho renamed Kilkis and Mississippi renamed Lemnos. With their 12in guns and 14,500 tons displacement at full load, they were the most powerful ships in the Greek fleet and they were the largest vessels ever operated by Hellenic Navy. Both battleships sunk while at anchor at Salamis by German diver bombers in 1941.

5. The last British battleship and the final battleship to be launched in the world

HMS Vanguard was the last British battleship which participated in Queen Elizabeth's Coronation Fleet Review at Spithead on 15 June 1953 (video). She was the only battleship in service that time with Royal Navy and one of the very few in the world. HMS Vanguard, the only ship of her class, was the biggest, fastest and last of the Royal Navy's battleships! The ship was built during World War II and commissioned after the war. She was also the final battleship to be launched in the world. She had a displacement of about 50,000tons, length 248m, max speed 30knots and main armament of eight 15in guns in four twin turrets. She was never the absolute best battleship in any category, but consistently among the best in every important characteristic: speed, protection, battery (main, secondary, and AA combined), fire control, seaworthiness, habitability and range. And except that she is considered one of the best balanced battleship of all time, she is also considered one of the best looking. Vanguard was decommissioned in 1960 after a short career.
