American adversaries fear the B-2 Spirit and there is good reason for it.While stealth fighters like the F-35 and F-22 are difficult to detect using even low-frequency early-warning radar arrays, the B-2 is perhaps the stealthiest operational aircraft in service today, despite its being rather old.It is an engineering marvel with a flying wing design with no fuselage or tail.There are no operational combat aircraft like the Spirit.But now a certain upgrade will see B-2 being transformed into a deadlier platform for nuke delivery.In this video Defense Updates analyzes how B-2 Spirit is set to become an even meaner beast with RATS & cryptology?#DefenseUpdates #b2spirit #usairforce
