Any decent engineer would make the fuel part of the warhead.I wonder if the hydrogen fuel tank could be designed to increase the effect of the explosive charge carried on a fuel-cell powered one-way attack drone?

UK company introduces HAL10 launcher capable of deploying 10 WASP modular drones for rapid reconnaissance and battlefield surveillance.interestingengineering.com
Cool idea. Canada will want to recover and rebuild the engines…A key element in turning both attack and interceptor drones into a more effective reality: Low cost, disposable jet engines.

Air Force Awards Contract to Develop Small, Disposable Engines
The Air Force awarded a $29.7 million contract to Beehive Industries to complete work on its small, disposable Frenzy 8 jet engine.www.airandspaceforces.com
"Beehive says its 200-pound Frenzy 8 engine is part of the FAMM program through a prototyping effort to develop small expendable turbines.
"The Frenzy 8 can hit 100-300 pounds of thrust. Beehive says it is also developing a 100-pound variant, Frenzy 6, which has 100 pounds of thrust. The new contract is to complete vehicle integration, flight testing, and qualification of Frenzy 8 and begin manufacturing a test version of Frenzy 6, with options for for further development.
"Beehive is one of at at least half a dozen companies working on small engines capable of producing between 200 and 3,000 pounds of thrust for Air Force programs like FAMM and Collaborative Combat Aircraft—and that push is poised to expand in fiscal 2027; the service is requesting $973 million for FAMM between R&D and procurement and $1.37 billion for developing CCAs, among other efforts."
Tomahawk uses a 30 kg jet that generates between 400 and 1700 lbf of thrust, depending on model.
Kratos's Valkyrie uses a 2000 lbf engine, the Mako uses a 1000 lbf engine and the Firejet uses a pair of 80 lbf engines for a total of 160 lbf
Firejet Weight at launch 320 lb
Payload of 70 lb
Range 400 NM
Endurance 1.3 hours

Japan is deploying ultra-cheap cardboard drones built for swarm warfare and expendable combat missions — $2,000 expendable combat drones cost less than some gaming PCs
$2000 drones vs. millions of dollars worth of military equipmentwww.tomshardware.com
$2000-$2500
Can remain in the air for 80 minutes or travel ~50 miles with a 3lbs payload.
Can be assembled in 5-10 minutes.
Shipped flat packed, 500 can fit into 1 standard shipping container.
Trust the Japanese to come up with an Origami UAS.
I added the manufacturer's website, have a look at their transforming Σ-1 VTOL drone.
