Kompleks 1030M “Drozd” (“Thrush”) Active Protection System

Radar: 24.5 GHz
Threat Speed: 70 to 700 m/sec
Protected Angle: 40 degrees
Interceptors: 8 x 3UOF14 107mm rockets

Notes: Radar is range-gated to only see those projectiles within the threat speed band. It seems that Drozd production was small; only about 250 systems for the Soviet Navy's Naval Infantry's T-55's.

“Shater” (“Tent”) Active Protection System

Protected Angle: 200 degrees
Interceptors: 20 x Casettes

“Dikobraz” (“Porcupine”) Active Protection System

Arena Active Protection System

Total Mass: 1,100 kg
Reaction Time: 0.07 seconds
Threat Speed: 70 to 700 m/sec
Protected Angle: 110 degrees horizontal, 15 degrees vertical
Power Consumption: 1 kilowatt at 27 Volts
Number of Cartridges: 22 to 26

“Drozd-2” Active Protection System

Threat Speed: 70 to 700 m/sec
Protected Angle: 120 degrees
Rockets: 10 x 3UOF14 107mm rockets

TshU-1-7 Shtora-1 EOCMDAS

System Weight: 350 kilograms
Laser Field of View (Claimed): 360 degrees horizontal, 25 degrees vertical
EO Interference Emitters: 20 Degrees horizontal, 4 degrees vertical (0.7 to 2.7 mkm band)
EO Emitter Power Consumption: 1 kilowatt
Smoke Grenades: 12 x 81mm 3D17 Anti-FLIR grenades (Bloom in 3 seconds, last for 20 seconds; and defeat 0.4 to 14 mkm band)

Kontakt-1 ERA

Explosive Panel: 4S20 (0.28 kg of HE)
Typical Weight: 1,200 kg
Effectiveness: Degrades HEAT

Notes: Tanks upgraded with Kontakt are given the V suffix (“vzryvoni” - “Explosive”). NII Stali claimed that this first generation ERA would degrade enemy projectiles by up to the following amounts:

125mm missile warhead: 86%
125mm HEAT projectile: 58%
93mm LAW: 92%

Kontact-5 ERA

Explosive Panel: 4S22 (0.33 kg of HE)
System Weight: 3,000 kilograms
Effectiveness: Degrades HEAT and KE

Claimed protection vs Sabot: 250+mm Equivalent RHA
Claimed protection vs HEAT: 600+mm Equivalent RHA

Composition:

15mm Hard Steel Frontal Plate
35mm of Explosives
20mm Steel Rear Plate

Notes: Defeats Kinetic Energy Penetrators via placing large amounts of shear strength against the penetrator via the outer plate's movement, causing them to snap. Additionally, the penetrator nose is blunted via a gullotining effect that chops off the first couple centimeters of the rod. Apparently the difference in penetration for a hypervelocity rod penetrator with a blunt nose and a sharpened point is about 20-30%. Due to the requirement for each panel to be set up at the right angle for maximum protection; Kontakt-5 must be part of a comprehensive armor package; rather than as a bolt-on modernization package as was the case with Kontakt-1.
