Colombia has Derby missiles for their Kfirs C.10

thanks. i stand corrected.

the next question is which upgrade (the newest cheetah, newest kfir, or the newest f.1)
has the radar range to exploit these medium range misiles.

They’re not the same length. Derby is 3,6 m long, mica is 3,1. Weight wise they’re similar though, derby being only 4 kg heavier. these is data straight from rafael webpage. Which is why i find the double the warhead claim a bit dubious.

It would seem mica has rocket motor of similar proportions to derby’s, though. Compared to its body length, derby has a fairly short rocket motor. My personal guess would be that derby development was constrained by python base design – so with the forward control surfaces the designers had to stick a lot of subystems aft of the control fins, closer to middle of missile.

At the same time, lack of mid body wings seems like another result of python starting design point. While a valid choice for highly maneuverable short range missiles, lack of mid body wings may result in lack of lift during the cruise stage, requiring greater angle of attack and producing more drag – meaning less speed and thus less range.

In the end, i would expect derby not to outperform mica kinematics wise. It may even be slightly behind mica in that regard. Even maneuverabilty wise, control surface at the end of a missile seem a bit more effective than surfaces at the 1/4 length of the missile, especially considering the shift of center of mass as fuel burns out. The distance between center of mass and control surfaces seems to be slightly on mica’s side.

Though actual, hard data on either missile is very hard to come by.

thank you my chubby japanese hamster.

the data were just generic wikipedia ones.
about Derby, yeah that seems to be the consensus around its kinematics. that it is hampered by being based on the derby. although the anti-mica crowd says the mica is a compromised design that can’t decide if it wants to be a short range or medium range missile either.

back to the derby, if its design is problematic.. why would they continue to use it on the new I-Derby-ER which claims double the range at 100km, but seems to keept he same shape

Forget the timelines, technologically I can’t see much difference.. The RDY3 is based on RC-400 which is basically a scaled down RDY2 of the Mirage 2000-5, is this radar really more advanced than EL/M-2032M? When you look at the ASTRAC MF2000 cockpit, you will recognize the same displays and the same HUD as once used on Spanish F1Ms.. In other words, most of the hardware is recycled stuff from Dassault’s previous programs, plus welcome addition of MICA and AASM.. Not saying it’s a wrong approach, just that it isn’t really all new..

Mica is a big game changer, if that is the case I think the Moracas F.1 is superior to the cheetah. the 530 is an unreliable missile, even though people in the other thread were fawning over it. it is as useful as the old AIM-7. but the MICA is deadly.

I don’t think the Cheetah has anything comparable. maybe the KFIR and Derby but havent seen any customer actually order the derby for their kfir

what ever the late model in production for Gripen and same for F-16.

I am not looking at India specific model but generally speaking how has Gripen stacked against F-16 in exercises ?

Gripen won. in Thailand.
