Testing

In November 2017, a successful test of the 53T6 interceptor was carried out. Target speed up to 3 kilometers per second (53T6 speed 3), acceleration overload – 100 G, preload maneuvering – 210 G.

Structure

A-135 consists of the Don-2N battle management radar and two types of ABM missiles. It gets its data from the wider Russian early-warning radar network, that are sent to the command centre which then forwards tracking data to the Don-2N radar. The

Deployment

There are at least 68 active launchers of short-range 53T6 endoatmospheric interceptor nuclear armed missiles, 12 or 16 missiles each, deployed at five launch sites. These are tested roughly annually at the Sary Shagan test site. In addition, 16 retired launchers of long-range 51T6 exoatmospheric interceptor nuclear armed missiles, 8 missiles each, are located at two launch sites.

Successor

The successor system, dubbed 'Samolet-M' (and more recently A-235) will employ a new, conventional, variant of the 53T6 missile to be deployed in the former 51T6 silos. The new PRS-1M is a modernized variant of the PRS-1 (53T6) and can use nuclear or conventional warheads. It can hit targets at ranges of 350 km and altitudes of 50 km.
