Project history: These three small diesel submarines were intended as prototypes of a mass produced ASW submarine, which would ambush enemy submarines as they emerged from their bases. The principal requirements were quietness, low cost and an effective passive sonar, the latter being carried in an enlarged bow sonar dome. They were later criticised as too small for habitability or for sea-keeping, and Tullibee was an attempt to update the ASW submarine (SSK) concept. In view of limited resources available for new construction during the early postwar period, an SSK conversion of fleet submarines was developed as a mobilization measure, and the GUPPY submarine conversions were all designed to permit later modification to SSK standard.
Modernizations: None.
Naval service: No significant events.
