35mm? Is the glass a fresnel lens then?

 

Very obviously, when you see one close up

What were the map sizes on those film frames?

I never have investigated for that detail.

 

Like did map boys copy a specific map area from paper map for you as positive film in specific size (square kilometer per frame, like 1:2500000 in 36x24mm frame size) so one frame could show 90x60 km area.

 

Like did the system be able hold multiple frames that got switched between, and aircraft position synced to it on waypoint?

Edit

Extranajero beat me to it!!

 

 

Have a look at:

Although this is the Tornado Moving map display, the Tornado/Harrier/Jaguar moving map are very similar in operation.

air combat sim podcast brought bad news regarding the FRS1. Doesn’t look like it’s happening due to confidentiality of systems. Very sad. Would have been such a nice addition to the falklands map.

Ah, that is sorry to hear. It is so central to it. Any word on if they'll go for a Gr.Mk.III/A instead? The map should have at least one 1980s Harrier variant that was deployed to it in that period!!

It'd be a shame if the only Falkland war flyable aircraft were the Mirage III and the Pucara (although I'm honestly most excited for the Pucara).

Yeah at one point prowler mentioned in a discord that the Gr.3 was a possibility instead. But I'd also guess its pretty far out. Apparently the issue with the Frs.1 is the radar, as they can't get the docs on it.

Is there not some way they can use their creative licence and make an educated guess. There are some very intelligent developers out there and I’m sure they could get it pretty close to the real thing. (Radar wise) I mean what did we used to do years ago. I remember Microprose Dogfight had the Sea Harrier FRS1 modelled and I guess permissions weren’t a problem, is it just a case that ED won’t allow a simulation of the aircraft without sufficient data to make it dead accurate? The falklands map without the FRS1 the aircraft that claimed what was it over 20 aerial victories, will be a bit of a let down.

Yep, unfortunately such as it is with the UK MoD, classifying everything.

The only thing I've seen so far of its RADAR is a very brief clip supposedly of Blue Fox, from an old-ish Harrier documentary I found on YouTube (I've got it downloaded, but it since seems to have been taken off YouTube), I'll get some screenshots:

Spoiler

Search in PPI mode (presumably for air-to-surface attack):

2pAQ5uQ.jpg

Transitioning to track:

2Jtw9Ct.jpg

Track:

O34XalB.jpg

In "Modern Fighting Aircraft Harrier" it describes the RADAR as having the following modes:

  • Search, with either single scan or multi-bar:
    • B-scope
    • PPI
  • Attack, supporting intercept and lead/pursuit or chase.
  • HUD-cued weapon aiming for air-to-surface attack
  • Boresight/air-to-ground ranging
  • Interrogation

As for the rest? We only know that it's I band, and is pulse-only (likely no LDSD capability).

Owing to the small size of the antenna, I'd say it's reasonable that its range is probably quite low.

Yeah, all probably correct, but its not really enough to build much of model on. Honestly if there were only tac man level descriptions of the modes that would likely be enough plus some "janes" numbers for range.

According to the podcast referenced above ^^
The radar is still classified as it is the grandfather of the Typhoon radar (ok, ok, the Raz guy calls Blue Vixen not Blue Fox… but either way refs apparently aren’t available)

BUT on the other hand, TG / HB are modelling the Typhoon anyway 😳 Do the German and British Typhoons carry different sensors???

If the Typhoon radar can be / is being modelled, then Raz need to go for a coffee, quick like

 

I do like the idea of a GR.3 as a fallback, but it’s a pretty poor second to the FRS.1

 

oh, and to all the folks not clear on the SHAR being unique compared to the other Harrier versions - go look up it’s A2A combat stats😉

Yes but the radar is the same. TG/HB have a full deal with the Typhoon consortium though, RB have nothing like it in place with the British MoD, hence the lack of documentation.

And tbh, having all aspect AIM-9s against opponents with only rear-aspect missiles operating at the limit of their range did far more to make the FRS1 successful in the Falklands than a mediocre search radar ever did (as you said, the Blue Fox is not exactly the Blue Vixen). The GR.3 can stand in perfectly well for it imo.

The community is already complaining about what realism is and is not, And would cause alot of crying that it should and should not be or do. Im sure there are some good modders out there tho.

Based on what I’ve previously read I can’t see that the GR.3 would make a viable FRS.1 stand in on any level 🤔 (dedicated A2G role, no radar)

particularly for the Falklands conflict, the FRS.1’s role was fleet defence first and foremost. Yes, the US provision of the 9L was key to the combat record, but if you read Sharkey Ward’s account, the Blue Fox was an asset for the Invincible’s 801 squadron at the very least

With Blue Fox it seems we are very much talking about radar being used as a basic search tool aren’t we?  No advanced targeting or involvement in weapons employment. Quite similar to WW2 other than the fact after closing the aircraft has IR missiles to attack with.

Just so people understand what’s available, or not…

Reading Harrier 809 at the mo - provides a better insight into the comparative capabilities of the FRS.1 and GR.3, and their crews, compared to the Shar pilot memoirs.

Blue Fox as a search radar to aid intercept - yes, with FC from the ships…

… but also providing gunsight HUD reticle / aim point, which the GR.3 didn’t have (and that the RAF crews in Shars weren’t as familiar with???)

It also had surface search/attack modes. Also, I assume it might have had some way of doing basic slant ranging of ground targets for things like CCIP deliveries. OR maybe not.
