The M-84AS1 and M-84AS2[6][7][8] is a new series of modernized version of the M-84 main battle tank designed by Military Technical Institute Belgrade and produced by Čačak in Serbia. First prototype version designated M-84AS1 was presented in 2017. and later versions of AS1 and AS2 with numerous improvements over first variant was presented in 2020. Latest variant's AS1 and AS2 incorporates newly developed modular Explosive reactive armour, modern Battlefield management system and fire controls system, Remote controlled weapon station and numerous other new subsystems.[9] AS1 and AS2 are developed in parallel and differs in number of same modernized subsystems implemented and some specific turret modification regarding RCWS and commander hatch and equipment implementation and represents two slightly different modernization versions of same M-84 tank with latter AS2 probably to be used as it becomes available firstly as platoon commander tank.[10][11]

Design and development[]

History[]

The imperative for modernization of Serbia aging M-84 fleet gave numerous tasks for Military Technical Institute Belgrade and Serbian industries. First prototype of M-84AS1 that was criticized because of some lacking in design was presented in 2017.[12] New version of AS1 followed in 2020.[13][14]

M-84AS1 old version presented in 2017

Current development[]

After initial prototype lacks in design(bad reactive armor coverage, bad sensors placements and low situation awareness) was recognized and corrected new modernization package was developed that will incorporate some solutions previously developed for M-84AB1 and previous first prototype from 2017.[15] with total of nine new subsystems integrated in first phase for M-84AS1 and additional 12 in second phase for M-84AS2.[16] New improved fire-control system is now developed with integrated day/night sight and new sensors. New forms of passive and Active protection system are developed. Protection against Top attack[17] missiles like FGM-148 Javelin is increased by using better composition of modular Explosive reactive armour that protects top of turret and soft kill Active protection system that is using Smoke grenade with Infrared smokes to create Smoke screen in order to block missile guidance. Day/night, thermal cameras and commander scope with 6 low light cameras[18] with other sensors increase Situation awareness of tank crew. Early warning sensors for detection of radar,[19] laser designation[20] and launching of rockets are coupled with automatic delivery of Smoke grenade towards threat to achieve protection. Second generation (comparable to third generation in other countries) of domestic Explosive reactive armour ERO-19[21] better than Kontakt-5 and comparable with Relikt is developed to protect against newer tandem charge HEAT warheads. Additional slat armor for protection against rocket-propelled grenades is also present.[22] Automatic fire extinguisher[23] capable to react in milliseconds with modern UV sensors for fire detection is added to stop explosions in tank compartments. New type of RCWS with 12.7mm machine-gun is added so commander can operate safely inside turret.[24] In total about 21 news subsystems are developed to increase survivability, mobility and precision of M-84AS1 and M-84AS2.[25] CBRN defense is increased with new sensors and automation process.[26][27] New tank gun 125mm[28] with modern thermal sleeve will be produced in factory and new ammunition[29][30] with better penetration and explosive characteristics including 125mm Airburst round.The APFSDS shell that is being issued to the tank is known to have 500mm of penetration at 2 kilometers range.[31][32]

Numerous companies will participate in production of many tank subsystems while Čačak[33] will be finalist for modernized tank under a guidance by Military Technical Institute Belgrade.

Producers involved in production of M-84AS1 tank and subsystems are:

  • , Čačak - reactive and other armor,[34] overhaul and modernization center[35][36] and finalist for new tanks
  • , Subotica - automatic loading system [37]
  • Sloboda Čačak - ammunition[38] and smoke discharge units
  • PPT Namenska, Trstenik - hydraulics, transmission parts and turret movement system[39]
  • , Zemun - optics, gyroscopes and gyroscopic devices and Fire-control system with software, electronics and electronic elements of active protection system[40]
  • ,[41] part of Zastava arms, Kragujevac - tank tracks[42]
  • 14. oktobar, Kruševac - finalist,[43] modular tank engine manufacturer, engine and transmission parts, shell parts for ammunition[44][45]
  • Yugoimport SDPR, factory - 125mm gun and barrels,[46] welded turrets, rcws, radio-logical-chemical subsystem, fire suppression subsystems[47][48]
  • Niš - detection of cumulative charge breach for automatic fire extinguisher, tank ammunition fuses[49][50]
  • ,[51] Belgrade - UORZ -Radar warning and direction finding system - part of protection system
  • Zastava arms Kragujevac - machine-guns 12.7mm and coaxial 7.62mm

Effectiveness[]

Many improvements that are adopted for M-84AS1 and M-84AS2 Serbian domestic modernization, gives better final results than some other current modernization programs developed for T-72. While basic armour of some T-72 versions is better than basic armour of M-84, additional newer and better placed modular Explosive Reactive Armour[52] will provide better cover and protection and new systems will provide much better additional situation awareness with better gun and ammunition. The new tank variant will feature an improved engine over a regular T-72 (increased from 780 to 840 horsepower), that will give an overall edge in combat to M-84AS1 compared most other modernized T-72 variants. In terms of protection, it is often considered even better than its Russian T-72B3 counterpart. [53][54][55][56]
