Phased array lasers have been invented but that doesn’t solve the problem of atmospheric attenuation or beam divergence.
MiG-31 I’m going by your own image which plots the power on target at specified ranges with specified laser powers. E.g. at 20km range with a 1000kW laser, the power on target is 39kW.
Ah okay, page 54 last para gives specifics. At 5km the spot size is 75cm^2, so at 20km it will be 16x75cm2 = 1200cm^2. With a 100kW laser Figure 28 shows 39kW on that target area at 10,000m altitude and 20km range. So that is 32.5W/cm^2. After many minutes that could probably cook a turkey. To get a useful 1kW/cm^2, you would need approximately 3MW and 20km would hardly keep you safe from MRAAMs or LRAAMs.
May’s deal is more like a cold dark black hole.
I read a study on using them as a CIWS and for a 10km range, an estimated 1MW was required, but I guess that does focus on sea level engagements where the air is denser. I guess if we multiply by 4 to allow for the change in air density and assume that beam divergence is not a factor then 40km could be possible. But the problem is that with beam divergence the power density at twice the range is quartered, so you need 4x the power for twice the range and an A-60 is no small aircraft. Then you have the problem of one large aircraft vs 4, 6 or 8 smaller fighters who will all be firing missiles, while this laser is taking many seconds to cook its way through one aircraft. I’m also not sure how to interpret those results. 39kW across say 5m^2 isn’t that much per square cm, in fact it’s less than 1W per cm^2 or less than a laser pointer. Is that really effective at much besides annoying the pilot?
I don’t think a no deal is that bad. Most research seems to suggest that May’s deal will lose 75-80% of the lost exports under a no deal scenario, except with a no deal scenario we can tariff EU imports and look to replace them with domestic stuff or cheaper non-EU alternatives (especially for food). We would also save paying the EU tariffs on non-EU imports, collect revenue via WTO tariffs on their exports to us and free up space in the over-stretched prison system by repatriating EU convicts. We would also maintain the integrity of the UK internal market. No deal a more valid proposition than May’s deal.
Laser in atmosphere has very limited range. About 10km for 1MW. That’s useless against Meteors and AMRAAMs, or even ASRAAMs and Sidewinders.
400km range from a Redut system? Can anyone explain?

A Canada-style FTA with the EU would be the easiest thing in history, but it would still be subject to NTBs and hence worthless.
Your £350m comment – the bus never said that at all. It said, “we give the EU £350m per week…” – TRUE. …”Let’s fund our NHS instead.” Both completely valid statements.
Only a French veto has prevented Turkey joining the EU thus far. Both Cameron and Blair were strongly in favour of it.
We hold a lot of the money they want. I’m quite sure you can validly metaphorise that as cards.
Let’s look at Remain lies:
“The only money NI get is from the EU.” – Nope it runs a large deficit covered by the UK and every penny they get from the EU comes from the UK first.
“The EU has improved workers rights.” – On paper maybe, but the number of people being paid below minimum wage, working in ‘prison-like’ conditions and being put out of work/business by illegal labour has increased and wages have also been driven down.
“One in every 10 jobs are due to us being in the EU.” – And more than one in 10 of them are taken by EU migrants.
Also, how much overspent would Remain be if we counted all EU-funded research papers and pro-EU media outlets?
I’d like to see a breakdown of the scores in separate categories as per the Swiss evaluation. That would allow the errors to be spotted.
At least we know one thing, Brexit wasn’t about racism and xenophobia after all, otherwise May’s deal would be absolutely fine. Funny that nobody’s mentioned that.
Agent K – Nobody is dumb enough to fall for a referendum that splits the Leave vote in two. There can only be two options. And I will say again, that there is currently a court case to decide whether we can even revoke article 50 and rejoin on the same terms, so nobody knows what remaining will mean, not that they would know what the implications of being in the EU in 20 years time would be anyway.
If there was a 3-way referendum split as follows:
No deal – 30%
Deal – 25%
Remain – 45%
Then IMO the result is that there is a 55% majority in favour of leaving, so Leave wins, and a Leave majority in favour of no deal, so no deal wins!
Bruce, I disagree because it would be cheating. If you have two options for leave and only one for remain, you are splitting the leave vote, which is unfair. Additionally, your argument is false, since we never knew what joining would mean in the first place, nor do we know what remaining would mean now. We don’t know what will happen with the EU 10-20 years from now, nor do we know if we’ll even be allowed to revoke Article 50 and rejoin on the same terms.
It should also be noted that the Leave vote was 419 constituencies vs 231. So remaining is politically unfeasible even if remain were to win, because Leave would still have the majority of the seats, and it would make the country ungovernable. I also don’t believe in holding two elections on the same thing because it encourages scare tactics and media fear-mongering like we’ve seen over the last 2 years, aka battering the public into submission.
Agent K – See Lord Bamford of JCB.
Three times as much coming in as going out as regards goods. If we can replace more than 1/3rd of them with domestically produced items, we’ll be doing better even if all exports to the EU are lost and we’ll save £10bn/year and make another few £bn on tariffs.
Agent K – Some existing business leaders don’t support it and their thoughts and opinions have been given an unduly large share of the air time.
