VERVIEW: The ROMEO class SS (Type 33) is a 2-shaft, diesel powered attack submarine.

DETAILS:   The ROMEO class was a further development of the ZULU and WHISKEY-class. The Romeo class was designed to conduct anti-surface ship operations using torpedoes and to execute mine-laying assignments off hostile ports. It has virtually no anti-submarine capability, due to high noise levels and inadequate sensor fit.
