"We don't know what's going on: gunboats alpha, charlie and gamma just dropped out of communications, transports three through seven are on fire and the escort transport has been broken in half. What's going on - there's nothing out there?!"
―Rebel officer

The Ronin-class Stealth Frigate is a UNSC Heimdall-class Frigate modified for stealth operations. It is the successor to the Shadow-class Frigate and bears some similarities to a normal Frigate, with a highly modified airframe that's been lengthened and modified to accept the new stealth systems and make room for its stealth abilities its stealth technology. The Frigate mounts the same technology as the Minerva-, Obsidian- and Cerberus-class Prowlers but with differs in how it is used. It focuses most of its stealth systems to masking its engines, the MAC capacitors and the nuclear arsenal. Externally the hull has been streamlined into RADAR resistant shapes. Thanks to the new technology used for Thunderstorm and Archer launchers even when on the offensive it is nearly undetectable. The downside to this powerful vessel is how difficult it is to maintain its stealth abilities. It is outfitted with a squadron of Scythe Stealth Fighters to ensure its protection.

Anansi-class Stealth Frigate

The Anansi-class Stealth Frigate was a subclass of the Ronin-class. The Anansi-class was aesthetically the same as the Ronin-class, but had an W/AS M21A 'Tsunami' DIC replacing its MAC gun. This subclass was employed extensively during the latter stages of the Necros War.

UNSC Comments

"Only two times has our ship ever been detected: once when we burned through orbit and another when we had to resort to using our Lasers to defend ourselves during a siege run when we ran outta missiles."

"Reason we can launch stealth attacks in space? There's no sound, you can't hear us. You might see some sparks from our MAC rounds, but we've already moved on by then. Of course, operations in orbital positions or in gas clouds is another matter."

"These things are bloody righteous; they can lay in wait for weeks on end, just waiting for their prey.."
