EKV is developed according programmke ground system BR interception on the middle portion of the flight «GMD». In 1998, under the «GMD» allocate more than 1.5 billion dollars. The main contractor — concern "Boeing". The approximate price of the 1st EKV will be around 25 million dollars.
The main device EKV:
— infrared sensors;
— on-board navigation system;
— Several specialized antennas;
— maneuvering engines;
— system cryogenic cooling;
— bortovik powerful;
According to its dimensional features of EKV resembles a small satellite. In general, EKV can safely be called one-time companion, which after the execution of the main tasks (liquidation purpose), eventually explodes.
EKV is the carrier rocket «GBI», which is set at the end of extra-atmospheric complex liquidation. GBI EKV to be installed in underground bunkers in all states of the country for defense. When the remote detection of ICBM center «GMD» launch a recommended system of interceptor missiles to the venue c ICBM with the same input data refreshed its seat in the EKV from satellites and radars.
Immediately after the launch of a GBI EKV on the last run of cryogenic cooling system for cooling infrared sensors to hundreds of degrees below zero (this is necessary for the detection of ICBM warheads that are on very low temperatures remain warm enough). IR sensors outside the atmosphere of the complex destruction capable of detecting the smallest in the surrounding thermal carriers.
After about three minutes of flight (1500 km to the detected target) EKV separated from the carrier — GBI. Upon separation, he abruptly leaves aside to avoid a possible collision with a vehicle. Moving speed approaching the target of about 35 000 km / h and it is not limit to achieve and can be more than twice the speed. At these speeds, EKV warhead is not useful — he will be a huge missile kinetic "bullet".
These speeds are claimed precision guidance systems, because the expense is going on here (speed EKV about 10 km / s). 1.5 thousand kilometers to the goal — it is about 100 seconds of flight EKV, for which he must find a purpose (the wrong purpose or not), just to sight, to find a "meeting place". Hit in the MBR (warhead) for its reliable destruction must take place in its "sweet spot" — an area about the diameter of which is only a few cm in a clear hit ICBMs and EKV absolutely annihilated.
In the development of complex destruction outside the atmosphere was a lot of technical obstacles, and to the present time, with the development of hardware components and radar systems EKV began to look quite finished weapons, and South American missile defense agency has allocated 636 million dollars (the contract) to the developer — the company «Raytheon» to create EKV.
At the end of October 2002 was held on 7 steals, 5 of which have been found to be successful. On this day were 16 test interceptions, eight of which ended in the defeat of a clear purpose. But the company «Raytheon» all have the ability to increment the opportunity to defeat the purposes of the applicable values.
The program GMD, which includes a GBI EKV, was the only defense applets that embodied (at the technical level) the interception and destruction of ICBM (warheads).
The main features:
— approximate weight — 64 pounds;
— length — 140 cm;
— diameter — 60 cm;
— average speed about 10 km / s.
