The Shaldag class Fast Patrol Boat (Hebrew: שלדג) is a small but fast class of patrol boats developed for the Israeli Sea Corps (ISC) and launched in 1989, it has since seen service with several other navies. Designed for security tasks where high intercept speeds are required, such as interdiction of terrorism and illegal smuggling. Its salient features are as follows:

  • High speed in rough seas, with good seakeeping and outstanding maneuverability
  • Exceptionally low slamming in all sea states
  • Dry decks at all speeds
  • Very spacious and accessible internal arrangement
