All this to say OTH is another Russian tub full of BS.
Ask the Australians. They seem satisfied enough with Jindalee to spend a lot on an upgrade.

Can’t speak for the Russians, but they’ve been investing and building OHTRs for a long time…..

The antenna in the photo has every characteristic of an OTH radar.

The Su57 is a supposed fifth generation stealth aircraft equivalent to the F22 and F35.

Yes it looks like an OTH array. However,
The Jindalee radar has arrays measured in kilometers and the Ausies started their programme since the 1980's and even earlier with input from the Brits and Americanss and are still developing' it.
​​​​I worked on the signal processing programme in the late 90's.

Im only learning about these radars through this war.

As you’ve been out of it for years, what’s your best guess where the technology is today regarding effectiveness?

Read again the description of the Russian radar. It was designed specifically to be transportable, so any comparison with the Australian system is invalid.

By their very nature OTH radars are extremely easy to identify and locate, so this one will have been an obvious target for Ukraine to destroy.

Under Project POTEEN, there was going to be an OTHR in the UK, with the transmitter site at RAF St Davids and the receiver site at RAF Blakehill Farm. But with the break up of the Soviet Union at the end of 1991, the Cold War was deemed over and the whole thing was cancelled.....

US arms should reach Ukraine in under a week following the vote, if it passes.

Might want to go ahead with that now, under revised Project PUTEEN.

............. and add China into the mix tho using OTH! I think they are using OTH-Surface Wave rather than Skywave but that's because they don't need the range in the 1000's of miles you get from Skywave. The US are also getting involved out there!

....... but the actual physical kit (the ROTHR) destined for installation in the UK, which had virtually been built when the Cx came through, still operates today - near Corpus Christie, Tx against the drug smugglers. It's had a few upgrades as you'd expect over the years but, essentially, that's where it still is.

As Xhorst says, who knows what the future holds............... but "son of ROTHR" is being deployed as we speak!

EU is certainly a You, and most of our NATO allies were/are in the EU (though the Brits bailed out a few years back).
To avoid visual clutter, amplification is in the spoiler. It's for you - the usual short-attention-span audience can't be bothered.

As to Greene, she's not my district so go and bitch to someone else about her.

The good news (thank you Uberteknik) is that the grid lock seems to be breaking, unless some other skulduggery arises.
As it's in the realm of politics, there's a chance something else will come up but I am betting that it won't.

Patriots for Ukraine: there's a nice play on words in there, maybe I need to start making T-Shirts.

Wouldn't it be nice if all countries made a pledge for continual support, not just one off packages?
I can hear it in the Ukrainian trenches "Okay lads, lets fight the Invaders again, at least until the bombs run out again".
What price all that blood being spilt.

True, but the Senate is all for this aid and there will be no problem passing it; they have previously sent a Ukraine aid bill to the House which didn't act on it. Monday signing maybe?

From the New York Times https://www.nytimes.com/2024/04/20/u...-military.html
Shipments of American weapons could begin flowing to Ukraine again soon after a long-stalled aid package becomes law, U.S. officials say, with goods from the Pentagon’s stockpiles in Germany to be shipped quickly by rail to the Ukrainian border.

The measure would provide the Ukraine war effort with about $60 billion. A sizable amount is set aside to replenish U.S. defense stockpiles, and billions more would be used to purchase U.S. defense systems, which Ukrainian officials say are badly needed.

In a statement on Saturday after the House approved the aid package, President Biden urged the Senate to swiftly take up the measure to help meet Ukrainian forces’ “urgent battlefield needs.” It was expected to do so as early as Tuesday.
