A target ship is a vessel — typically an obsolete or captured
warship
A warship or combatant ship is a naval ship that is built and primarily intended for naval warfare. Usually they belong to the armed forces of a state. As well as being armed, warships are designed to withstand damage and are usually faster a ...

seaborne target
Seaborne targets are vessels or floating structures that are shot at for practice by naval or air forces. They may be remotely controlled and mobile, or towed behind other craft, or just set adrift in the sea.

for naval gunnery practice or for weapons testing. Targets may be used with the intention of testing effectiveness of specific types of ammunition; or the target ship may be used for an extended period of routine target practice with specialized non-explosive ammunition. The potential consequences of a drifting wreck require careful preparation of the target ship to prevent pollution, or a floating or submerged collision risk for maritime navigation.
Rationale
![Declassified Image of USS America Sinking by the Bow After Scuttling Charges Were Used After Four Weeks of Damage Weapon Tests](https://upload.wikimedia.org/wikipedia/commons/a/a8/Declassified_Image_of_USS_America_Sinking_by_the_Bow_After_Scuttling_Charges_Were_Used_After_Four_Weeks_of_Damage_Weapon_Tests.jpg)
Sinking redundant warships is an effective way of testing new weapons and warships in as realistic a manner as possible.
Preparation

In the early 1930s the US Navy put considerable effort into the development of remote control ships and fitted the destroyer with improved radio controls developed by Lieutenant Commander Boyd R. Alexander, a radio design officer, and the Naval Research Laboratory in Bellevue D.C. for further testing and evaluation. The evaluation proved so successful that the US Navy moved up their plans for radio controlled warships and in 1932 the obsolete battleship USS ''Utah'' and the destroyers and were converted.

The sinking of ''Torrens'' was a display of firepower that provided some much needed positive publicity for the ''Collins''-class submarines, plagued by numerous technical problems and criticised over troubles with the combat system and noise reduction. Ric Shalders, commander of the Submarine Squadron said "the requirement of new submarine trials, the new need to test war-stock and the availability of the Torrens all came together to produce a very satisfactory result".
