Beholders, eh?
Well, a similar sort of vein, why don't we get them to call the manned version that flies around calling down air strikes...

... the "Orgrim's Hammer"?

"I'm guessing you'd have to have an extraordinarily good aim to hit something at 1.5km up in the sky"
Judging by that photo, its about 40 feet high by about 100 feet long.
1.5km = 7920 feet
So its like hitting an object at a distance of 79.20 feet that looked like an object 0.4 foot high by 1 foot long. So about the size of a shoe box. That sounds very possible. (Although I doubt it would do much damage).
I never start shooting after a plate of beans, so wind isn't a problem.
Anyway, 1.5km up means you're probably 2-3 km in a straight line to the target, unless you're directly underneath the thing with a load of pissed off 'merkin soldiers.....
It's still something you could shoot at with a missile though.
One word: SAM.
If they can take out a Tornado or a Chinook with a shoulder mounted rocket, is this blimp going to pose a problem? Or is the fact that it's cold and round mean it's invisible to IR or radar? Or are SAMs cleverer than that? I know nothing about militray technology.
The M107 12.7mm (.50 caliber) sniper rifle has an effective range of 1.8 km and a maximum range of 6.8 km. You wouldn't have any trouble hitting a blimp at altitude, even with stand-off range factored in. Poke a couple dozen holes in it and watch that blimp comes down quickly.
My late uncle Len played his part defeating the Hun during the Second World War by virtue
of being stationed at the end of Southend Pier in Essex UK.
The pier was acquired by the Navy and for the duration of the war it was named "HMS Leigh".
His primary task was to raise or lower the "Blimps" or anti-aircraft baloons.
An officer stationed at the start of the pier would use a hand cranked telephone to
give the required instruction. (The pier was over a mile long !)
Uncle did not find this task very daunting and became an avid sea angler.
He had to be deterred from sending parcels of fish home to South London as the postal service
was not very good. The postman took to hurling the stinking fish parcels up the drive.
Paris...well why not !
