It was introduced in 1983 on little number of old T-55 tanks and scrapped few years later.
Developed and tested in late 70s and entered production threafter. T-55 were not old, they were t-55A modernised, wich were very capable. Drozd was later removed from service, yes, but replaced by Arena in T-55 in the 80s
Just google it. Not sure if it was Drozd or Arena.
Trophy is designed against all types of HEAT rounds from all directions. Drozd protected only the frontal arc.
Drozd was made in the 70s, and upgraded to 360 coverage.
T-55 with Drozd were scrapped.
Drozd was old as hell, T-55 were replaced with Arena.
Trophy is designed especially against tandem warheads. Simle RPGs are not a threat to Merkava
.
This specific APS
cannot give protection against tandem warheads, we've been on this, it's phisically impossible, unless you go with a big shotgun blast wich causes collateral damages. Throphy was designed according to israeli doctrine, fight against limited insurgents who ambush with RPGs, and that's it.
