Actually, zepelin balloons are fairly rigid. Can soak up enemy fire without getting damaged to much.
A series of structural vulnerability tests were done by the UK Defence Evaluation and Research Agency DERA on a Skyship 600, an earlier airship built by the Munk team to a similar pressure-stabilized design. Several hundred high-velocity bullets were fired through the hull, and even two hours later the vehicle would have been able to return to base. The airship is virtually impervious to automatic rifle and mortar fire: ordnance passes through the envelope without causing critical helium loss. In all instances of light armament fire evaluated under both test and live conditions, the vehicle was able to complete its mission and return to base. The internal hull pressure is maintained at only 1–2% above surrounding air pressure, the vehicle is highly tolerant to physical damage or to attack by small-arms fire or missiles
That's a commercial vehicle.
Well sure,but do you think that a 25 kg bomb won't hurt it? Or any incendiary weapon? Incendiary bullets...
It's not unlikely that the bomb fails to detonate. Even if it detonates, most of the craft is heavily compartimentalized (Think hundreds, maybe more). The Comparement that's hit will most likely be destroyed. The adjoining compartements might start to leak, but small holes will seal themselves (rubber boats can do it, so my blimp can do it too). Damage will not spread far.
Also, neither the construction materials nor the flotation gas are flammable. The gas is helium, so it will actively counteract the fire. Carbon nanoweavers don't melt easily, so it's unlikely that the fire will do damage. It might even fail to penetrate. (It stretches and bounces very well.)
Thirdly, have you ever tried bombing a moving, stealthy and very agile target while speeding by at 4 times the speed and under heavy AA fire.
What's the charge meter for?
And also, which of the 3 ship's is flight ready? There's a difference between a supply ship and the massive airship.
