Anti drone drone.  I guess it's cheaper than shooting a missile.  It uses an electronically scanned Ku band radar to find/intercept enemy drones.  They must have figured out how to build them cheap.

Another video showing different uses for this UAV.

Yeah the video author made some changes to the design. Still, the underwater ignition is awesome. Looks as if a tactical nuke exploded underwater  :o

Hmmm... can't see Skylon on the new website! Maybe it's time to rename this thread or start a new one and call it "Reaction Engines Ltd - Synergetic Air Breathing Rocket Engine (SABRE).

I started this thread nearly 11 years ago as a die hard Skylon fanboy who hadn't got around to reading all his books on space exploration and rocket development. Now I'm a little bit wiser on the technical difficulties and economics of single stage to orbit and full reusability it makes sense that Reaction Engines is concentrating on SABRE for multiple applications and seems to be making good progress.

It's great to see SpaceX leading the way with making space access more affordable. However, Skylon still looks awesome  :D

don't be too harsch with yourself. Unlike so many paper projects, Skylon got a positive assessment by ESA some years ago. So it was - and still is - a little more than hype.

The revamp finds space for LAPCAT:

"During a 2008 EU-funded study called LAPCAT I, Reaction Engines found that a SABRE variant named Scimitar would be capable of powering a vehicle at cruise speeds of up to Mach 5. This was the first major government research contract and was worth €2 million. The LAPCAT I contract for the pre cooler represented the first opportunity to demonstrate its world-beating heat exchanger design and manufacturing capabilities."

It does look as if Skylon has been airbrushed out. That NASA analysis can't have pulled its punches!

This looks interesting:

Too true about Skylon, when I first saw it I could not stop looking at it.

Looking very antiquated, the concept of the 3-engined transport wasn't absolutely
dead after WW II, as can be seen by the Northrop -23/25.
Here it was SNCAC, using again this old formula for the NC.300.
Some data : 3 Wasp Junior engines, max.speed 265 km/h, range with 2000kg payload
1000 km, with 2500kg 500 km, take-off run approx.500m to clear a 20m obstacle.

By the way,

there was also NC.301,but no details are known.
