The defense contractor is the one that announced this week the Spirit’s arsenal is getting enriched, for the first time, with a long-range stealth missile. It’s the Joint Air-to-Surface Standoff Missile - Extended Range (JASSM-ER) we're talking about, a weapon the bomber successfully fired for the first time back in December, and an achievement we’re only now learning about.
The JASSM-ER is powered by a turbofan engine, and can reach distances of about 1,000 km (621 miles), according to Missile Threat, while keeping track of its target by means of an infrared seeker and even 3D models of it. It’s not easily detectable by enemy radar because of its shape and the materials used to make it.
The successful test back in December means that soon the Spirits will be fielding these missiles as well, although when that will be has not been disclosed. No other details on the test were provided.
Aside from the fitting of the JASSM-ER, the B-2 fleet is also getting as per Northrop Grumman “crypto modernization” and a Radar Aided Targeting System. RATS for short, it should allow “the B-2 to fully employ the B-61 mod 12 nuclear bomb.” The B-61 is America’s main nuclear gravity bomb, with mod 12 being one of the most recent variants of it.
