good points...

I seriously doubt Hydrogen was chosen for it's "greenness". More likely for it's energy density vs weight. Greenness? just spin...

I suspect the military wants the ability to deploy a platform to a given location - quicker than "lighter than air" platforms can get there.

THIS version: obviously not related to armed drones missions - it has a very different mission (at this stage of development).

Likely would be used in conjunction with other types of drones on military operations.

Or monitoring a border for smuggling (para-military/policing operations)? Talk of using these for US / Mex border ,  monitoring Gulf of Mexico, etc.... With weather issues, and limited quantity, a more quickly deployed choice than Dirigibles.

Thanks.  "Reforming" is the correct term--slipped my mind.  So long as natural gas (methane) is cheap, that is the preferred way to make hycrogen.   Electrolys is proposed for storing solar-generated electricity, although the "round-trip" efficiency is <<50%.

It's been my understanding (which may be wrong) that even in the case with an on-board pilot, a lot of bombing runs are done without visual inspection by the pilot.  He might be targeting based on info or a signal from someone on the ground, based on pre-determined coordinates or looking through a video display to enhance light, aim, magnification, etc. - no unlike a remote pilot.  The one exception is the remote pilot can have his / her mind on the mission without having the think about preserving his / her own life.

I'm waiting for the drones to start having more intelligence.  Possibly needing the remote operator only to confirm the shoot orders at the last minute.
