They could always build a stealth embassy, no?

Clearly an OTH radar could detect it.

Thats a pretty low orbit. But then again it doesn't stay up long enough for there to be significant decay. Plus it can reheat if it needs to.

Now THIS is something I didnt see coming...... RAF pilots could fly into battle at speeds of around 3,000mph in hypersonic jets, the Chief of the Air Staff revealed yesterday. Air Chief Marshal Sir Stephen Hillier said new engines could let warplanes race past enemy air defences at more than Mach 4 or four times the speed of sound.

 

The RAF and Royal Navy’s latest warplane, the F35 Lightning has a top speed of about 1.6 Mach while the US F22 Raptor is designed to reach 2.25 Mach. Sir Stephen announced a £10million two-year development programme into “High-Mach advanced propulsion systems” with Rolls Royce, BAE Systems and Reaction Engines. America, Russia and China are also actively developing hypersonic warplanes or missiles. Russia has developed Avangard, a hypersonic vehicle launched from a ballistic missile, which President Putin has boasted is “invulnerable to intercept by any existing and prospective missile defence”.

 

Sir Stephen, who said he wants the technology exploited “as rapidly as possible”,  said: “We have noted  very carefully what the Russians are doing.”

The British programme is seeking to marry hypersonic propulsion engines with existing warplanes.

One option could be to boost  RAF Typhoons or Lightnings by modifying their engines to benefit from some elements of hypersonic propulsion.

Speaking at the 2019 Air and Space Power conference in London, Sir Stephen said: “If we are going to maintain our technological advantage we have to move fast.”

He added: “Over the last three decades we have enjoyed an unparalleled advantage in air and space which has allowed us to do operations like in Iraq and Syria.

 

 

“But potential adversaries have spotted this and we face increasingly sophisticated and integrated air defence systems designed to deny us access to their air space.

“If we do not have access to our adversaries’ air space we have a problem.

“One way round that is speed, to go through it at hypersonic speed.”

Sir Stephen told the conference, whose delegates included by 46 military chiefs from 39 countries: “We must still be prepared for major military escalation, confrontation and conflict – especially as we watch our adversaries continue to invest in high-end military capabilities, across all domains.

“We must, therefore, guard against complacency because the advantages we have secured and depended upon for decades – especially in the air and in space domains – are being eroded.”

The MoD said hypersonic or High-Mach systems “are of growing world-wide interest”.

A spokesman said: “The extra speed developed enables new capabilities including decreased time to target; improved penetration in contested environments; and the ability to access previously unreachable areas.

“For a range of defence uses, speeds over Mach 4 are desirable.”

The main difficulty of achieving hypersonic speeds is that it affects the capacity of air-breathing engines.

Sir Stephen also hopes to start introducing “swarms” of drones within about a year.

The RAF is interested in unleashing large numbers of drones against enemies so that they overwhelm their defences and increase the battlefield information for commanders.

It is forming an experimental squadron, Number 216 Squadron, to accelerate the introduction of swarming drones.

* RUSSIAN air activity over the Baltic states is on course to have risen sixfold in three years, Sir Stephen said.

RAF Typhoons are currently providing air defence in Estonia following a four-month posting there in 2016.

Sir Stephen told the conference: “For anyone in any doubt about the levels of activity we are facing, note that since arriving in Estonia on the third of May this year, our Typhoons have already scrambled 13 times in response to Russian activity over the Baltic Sea – many more times than in the whole of our last deployment there in 2016.”

Later he said that compared to 2016 RAF jets have scrambled three times as often – but that was in two months compared to the previous four-month tour of duty.

 

British Reaction Engines limited of course have been working on a hypersonic engine for some while, it will be remembered about 10 years ago they were proposing a space launch vehicle called 'Skylon' as a Space Shuttle replacement. If they can build something smaller that is possible to fit in a fighter airframe (I would think a Tempest airframe would be more suitable) then it would be something of a gamechanger. It would mean manned aircraft would be able to operate in the regime above conventional airbreathing engines.

 

Basically, the RAF wants Firefox. :)

Someone should make a revised Bomarc.

Vertical launch from booster or horizontally without. Then scramjet to Mach 5 or so. Makes intercept (or not) then lands horizontally.

Give it folding wings so it can fit on a truck.

Not really - they're just part of the token tripwire. If the Russians wanted to they could easily shut down the airfield they operate from with missiles.  Amari has one runway - the HAS look abandoned and may have been built for smaller or shorter aircraft than the Typhoon anyway (though Su-24s were based there later on}. Satellite footage shows the Typhoons lined up on the apron rather than located tactically.

You are always such a downer. Though not wrong.

End of the day, only the US could possibly bring Russians to heal. Which is disturbing given our current leadership.

Nah, Vulcan B3. Big wings, BRE engines, nuke them from orbit its the only way to be sure. :)

Its still an exceedingly beautiful aircraft to look at. Im looking forward to seeing what the B21 looks like.

 

Apparently they showed a model of the B2 to Jack Northrop not long before he died. It must have been great for him to reflect that his hard work finally paid off.

Sweden onboard significantly increases the viability of the project. Japan needs to be next.
