It was always my understanding that the BlackHawk’s ballistic requirement were the capability to fly safely for 1/2 hour after flight critical controls had been hit by a 23mm high-explosive incendiary projectile, and that includes the MRH, Hub, Blades and MGB.
Not something I suspect the ‘Commercial' contenders have even thought about, let alone certified.
I say commercial, as even the AW149 is an AW139 (EASA JAR/CS-29 certified commercial airframe), with a 90 to 100cm cabin stretch, is it not?
