More or lessWhy do we still use T-55s as mine ploughs? Because, they are expendables?
2 years old seriously?Indian Army seeks active protection systems for its T-90S/SK MBTs
The Indian Army (IA) has invited responses from local vendors by 12 May regarding the supply of 818 modular active protection systems (APSs) to enhance the survivability of its T-90S/SK ‘Bhishma’ main battle tanks (MBTs).
In a 13 April expression of interest (EOI) the IA said the new protective systems for these tanks, which are “likely to remain in service beyond 2050”, are to be acquired under the ‘Indigenously Designed Developed and Manufactured’ (IDDM) category of the Ministry of Defence’s (MoD’s) Defence Acquisition Procedure 2020, and will need to have a “50% indigenous design and development content”. Prospective vendors will be permitted to enter into arrangements with foreign manufacturers to develop the equipment.
The APSs are required to have both hard-kill and soft-kill capabilities. The soft-kill component must provide both smoke discharge and infrared jamming effects, and provide audio-visual warnings when the tank is either lased or fired upon.
The hard-kill component is required to be capable of engaging shaped-charge threats such as rocket-propelled grenades (RPGs), anti-tank guided missiles (ATGMs), and high-explosive anti-tank (HEAT) rounds fired from tank guns. The protection level required was quantified at 90% against ATGMs, rockets, and RPGs, and 70% against incoming 125 mm HEAT rounds.
A non-required, but “desirable” request was for the APS to be capable of defeating kinetic energy (KE) projectiles. That said, the system is required to at least have upgrade potential to defeat KE threats in the future.

this deal went nowhereRafael Trophy APS to equip on Indian Army T-90S Bhishma MBT
A tweet posted by Kunal Biswas on October 26 shows a model of Rafael’s Trophy APS (Active Protection System) adapted to an Indian army T-90S Bhishma main battle tank. Some 3,000 tanks and other armored vehicles might be fitted with this APS following a major decision taken during a (Defense Acquisition Council) DAC meeting held in February 2021.
As written by Force India Magazine, the T-90S has space constraints and its Auxiliary Power systems might not be sufficient enough to support the APS, but the new T-90MS being procured has a new APU just behind the left sprocket wheel. However, the variant India would receive will be without Arena APS.
It is known that an APS can be evaluated primarily on the parameters — sensor threat detection range, reaction time, types of countermeasures, threat interception range, jamming resistance, interception methodology and multi-shot interception capability additionally engineering parameters such as size, weight and power consumption will also be considered. APS has two types of sensors active (Millimeter Wave radar, Light Detection and Ranging) passive (Laser Warning Receiver, Ultra Violet missile warning system) the sensor information is fed to the countermeasures which can be from soft-kill or hard-kill. The soft-kill countermeasures consist of multispectral aerosol smoke grenades which can blind all missiles including fire and forget missiles, Electro-Optical/ Infrared (EO/IR) jammers can jam Semi-Active Command Line of Sight (SACLOS) missiles which constitute 70 percent of the current missile threat. They are simpler systems that require directional information from sensors.
Hard-kill countermeasures use kinetic means to destroy, disable or deflect incoming projectiles, they require more precise positional information including direction, elevation, distance and velocity of the projectile. The future challenge for APS is in intercepting Armour Piercing Fin Stabilised Discarding Sabot (APFSDS) rounds which travel at velocities of 1,500m/s-1,800m/s which is six-eight times faster than missiles. Ideally, the Indian Army would look to incorporate both countermeasures to maximize the survivability by adding more layers to the proverbial survivability onion peel, Force India concludes.
