This unique book systematically breaks down the types and families. Propulsion: Thermal (Otto fuel II) driving a pumpjetġ0 years of research, analyzing over 160 incidents, condensed into a handy guide. The submarine launched Type-89B is seen as the Japanese equivalent of the Mk-48. Latest generation electric heavyweight torpedo for Russian Navy submarines. The improved UGST-M (aka Case) has is visibly distinct with a redesigned propulsor and fins. The Universal deepwater homing torpedo (UGST), aka physicist, is the main 533mm torpedo for Russian submarines. This Covert Shores Recognition Guide Covers over 80 classes of submarines including all types currently in service with World Navies. Get The essential guide to World Submarines Propulsion: Thermal (HAP / Otto fuel II) driving a pumpjet Speed: 80 kt reported (might be exagerated) Spearfish Mod-0 specifications (Estimated where necessary - reported data is vastly understated) The Mod-1 incorporates a single-fuel thermal motor and an insensitive warhead to improve safety. The two weapons have their own pros and cons.Ī prototype of the next-generation Spearfish Mod-1 has been tested. Generally on a par with the US Navy's Mk-48 ADCAP, the Spearfish was designed to tackle similar Russian (then Soviet) high-performance submarines. Mk-48 ADCAP specifications (Estimated where necessary - reported data is vastly understated)Ĭomparison of original Mk48 (left) and the ADCAP (right) As torpedoes generally improve, the Mk-48 stays in the top tier with the upgraded ADCAP (Advanced Capability) version. It was also designed to operate under the ice cap and, generally, in a wider envelope than most torpedoes. The Mk-48 was one of the first western torpedoes designed to counter extra-fast deep diving submarines such as the Alfa Class. If you do not see the torpedo you are looking for, please try back at a later date. It will be extensive but not necessarily exhaustive. This article will cover contemporary heavyweight (533mm / 21") torpedoes.
