I think I have seen some discussion on this earlier, so if this is a repeat.............tough.........

After getting Dobodura built up and moving in air groups, I found the base lacking in a/c support so I moved an extra base force unit there. For protection I had 3 squadrons of P-40's which I set on escort 50%. Before this bf unit arrived, I would get the usual 36 fighters intercepting during raids. After the unit arrived, my interceptor numbers jumped to 72! Thinking I had put my CAP on 100% and not realizing it after too many brews, I checked and they were still set on 50%. Then I checked my bf units, and sure enough, the new one had 2 SCR-270's. None of my other bf units in theatre had any and I was not used to the results. This is a two edged sword however since it plays havoc with fatigue. So, until those 2 sets are destroyed by malaria, I'll keep putting up max intercepts..............

BTW, will the new bug fix pertaining to malaria destroying radars carry over to other equipment like AA guns and such?

Yep, radar seems to allow 100% of available fighters to scramble. A -big- help (and some would say a SERIOUS advantage for the Allies). This is the drum Knavey likes to beat. He's working on contracts at the moment tho, and may not see this thread (*grin*).

Hi, Because radar allows the fighters on the ground to scramble, you do not need to set CAP as high. This allows more pilots to rest on days where no combat occurs.

Funny that no Japan units get radar of any sort ... just another huge advantage for the allied player...

Hopefully these units can still be damaged in base attacks with the new patch. While I agreed with the fix since they were never getting repaired at ALL, I hope we haven't swung full circle to where they can never be hurt now ...

They should make it so that if a Japanese ship with radar is in a base hex the base should get the same radar benefit as if the base itself had radar.

Are there any Japanese land-based radar units in the database, for custom scenarios, even if they don't exist in any of the regular scenarios? Would assigning ANY radar to a base give the same benefit?

But the ship has no direct connection to the airfield. I suppose they could use radio, telephone or signals. Depends on distance etc.

"Funny that no Japan units get radar of any sort ... just another huge advantage for the allied player..." - MrFrag

Actually, the IJN does get radar on several ships (altho not nearly as many as the USN). The "Yagumo" class destroyers are all equipped with Type 13 Radar (air search), and it appears that plunking one of these guys into your TF with your CVs, gives you "standard" radar benefits (100% scramble). There's also a class of CLs that has it as I recall. But you don't have to have the air search radar on the CV for it to be effective (it can be on any ship in the TF).

I agree tho, IJN is woefully (and a-historically) lacking in radar sets. Most of their BBs were fitted with radar (altho I'm not sure it's the air-search type). I posted a few threads for AAA/Radar upgrades suggestions for IJN battleships last week (I only listed BBs, because that's all I could find information on). But I'd also wager that many IJN CVs were fitted radar, or received it in refit.

Once source indicates only 1 set of this type built, but same source indicates it was installed on numerous ships. At least 30-40 sets built and used operationally. Type 21 was the first Japanese air search radar that was power rotated, previous models had to be hand cranked to rotate. It was also the first set that gave good enough target definition to obtain rough estimates of height.

Japanese Radar Of World War II
by Martin Favorite

Good information, Mogami. Looks very similar to what's on the Combined Fleet website. Maybe between both those sources we can convience Matrix that more Japanese ships should be eligable for a radar isntaliation if sent back during 1943.

Who cares about the ships, fight at night, the Allies are hopeless

The biggie is the land based, as the effectiveness of being able to keep rested CAP ready to pounce can not be overrated.
