You'll recall that, around the same time, the USAF set a 1,500-foot STOL target for the ATF.
They also demonstrated a ground mapping radar mod which was engaged on finals to a cratered runway and could identify a 50ft wide 1500ft MOS and safely land and brake the aircraft to a stop.

IIRC they also tested a FBW mod which could adjust for an engine out, loss of half a tail, 50% loss of controls etc and still allow the pilot full and free stick movement with the aircraft compensating.

Was that sort of stuff incorporated into the Typhoon/ F-35 FCS?

I get what you mean. All those imaging satellites are quick and cheap to build, and their launch and mission support are also very cheap and thus they impose no "cost-imposition problem." And in a major shooting war where carriers are being targeted such satellites and their ground control stations are completely invulnerable. Yeah shur.

With the pluses and minuses on both sides, it's a good thing we'll have both

Have you ever watched a space x launch onboard coverage?

Have you ever heard of cubesats??

What if the sats [cube or otherwise] are already in position???

So many questions but only one answer will becoming......

GR... pretty much. Schwacking everything out of LEO that can image ~1 m resolution is apt to be difficult and messy. But Yeah shur you can babble about Yeah shur if you want to make the problem go away, or better yet you can yell Rumplesnitz!

Surprised that this lengthy BBC News article has not already been linked.

Surely we’re not contemplating a kinetic attack on space based systems? Far better ways of using the gaming generation than that.

More importantly:

1. Satellites are great for seeing things that do not move, but not so good as tracking moving things such as ships. Not only is the field of view limited, but the ship moves, and whilst the satellite comes back to the same point in its orbit, the Earth has moved.

2. Exactly what some of resolution do you expect from a Cubesat? Have any had a Earth Observation mission? No? What does that tell you?

3. Cubesats are only so cheap as they hitch a lift with a proper payload such as a satellite being launched in Geosynchronous Transfer Orbit.

Your points are noted.

Interesting links -although they seem to be by the same company. I was assuming you were referring to imagery satellites. However many of the same limitations apply. The Western Navies have lived with hostile SIGINT for decades, including during World War Two. Counter measures do exist

Depends on how many you want to launch at a time - and the payload.

SpaceX intends to put 12,000 Starlink 400kg cubesats in two height layered constellations within the next 5 years, the payload capacity of a BFR when it enters service will be around 300-307 of them. Since the USAF is already talking seriously of becoming a major SpaceX BFR customer, how many do you think they, or the new Space Command, would have to launch in polar orbit to provide 24/7 one hour coverage?

Meanwhile, changing subject, the previous HMS Ocean has reached her new home.

Yes. Military grade high resolution imaging cubesats? Not so much.

What if they are? Cubesats can be neutralized even easier than higher orbit hardened military satellites. And that's just the satellites. You can effectively kill the entire satellite constellation by killing the few satellite control ground stations. Or are they magically invulnerable?

So many questions but only one answer will becoming......
There are plenty of answers. None indicate that carriers are inherently more or less vulnerable than land airbases and none indicate that satellite constellations, even ones numbering in the thousands of individual satellites, are invulnerable.

Not quite sure what your angle is Ken, I'm merely pointing out that technology advances and costs plummet.

An example is the planned 12,000 plus constellation of internet cube sats proposed by spacex to cover the continental US.
EG.BFR is said to have a capacity of 250 per launch, fh around 50@ 850 kg each.
So a determined foe with launch capability even less than say F9 could, with multiple launches, seed the area of operations of a carrier group and continue to do so.
As for speculation who says every 850kg cube sat actually needs to be for surveillance ....

Does this technology apply to military grade imaging satellites?

Seed the area of operations of a carrier group?! Do you imagine these satellites can hover over an "area of operations?" Regardless of the number of satellites that are so seeded, it takes ground stations to make those satellites of any value. Are those ground stations invulnerable? Can the links to/from the satellites be jammed? Can the satellites by blinded/soft killed with a directed EMP burst?

Judging by what a none nuclear Swedish Sub did to the Ronald Reagan and Battle Group during an exercise some years ago, and lived to tell the tail you do not need to have massively expensive systems. The cost of the said sub was equivalent to one of our much vaunted new fighters. As the Russian defence minister said about the new carrier when commissioned "it is just a big target". I know the idea is about power projection, but given our straightened circumstances and our potentially even poorer economy, are we still in the power projection league, or do we want to be ?

yeah that's a great idea ken.

however bearing in mind the Russian tactical docrine in the first use of nukes, you may have inadvertently "hit the nail on the head"

Everyone pretty much concedes that once nukes are in play, all bets are off.

HMS Queen Elizabeth has arrived in the USA. Mayport, Florida to be exact. Exciting weeks ahead.
