Black Cat-class subprowler

Black Cat subprowlers are small ships used by the UNSC and ONI. Designated as "sub-prowlers," they have extremely limited capabilities and are used mostly as exfiltration craft to escape combat situations with stealth and ease. The ships have slipspace capacitors, but only enough charge to use them for about four hours. Black cats are routinely used on high-risk ops, so that special forces can retreat quickly and easily. It appears that they replaced the Calipso exfiltration craft.

Eight such craft were inserted for the Spartan-IIIs during Operation: TORPEDO, but only one was used because only two Spartans survived the engagement.
