[FONT=Arial,Helvetica][SIZE=-1]Derby, the name given to the missile for the export market, employs an active radar seeker developed by Israel Aircraft Industries. It is an all-weather system with a look-down/shoot-down capability, according to Yigal Ben-Hanan, Rafael's director of air-to-air and defense systems. Derby also has a programmable advanced electronic counter-countermeasures (ECCM) capability. Ben-Hanan said Derby can be operated in two modes. [/SIZE][/FONT]
[FONT=Arial,Helvetica][SIZE=-1]One is a lock-on after launch mode for long-range engagements in which the missile employs inertial guidance immediately after launch until the seeker is activated and homes in on the target. In the lock-on before launch for short-range engagements, Derby's seeker can be slaved to the aircraft's radar or the pilot's helmet mounted cueing system. The seeker is activated before launch and guides the missile all the way to the target. According to company officials, Derby has capabilities similar to the Rafael's third-generation Python 3 infrared-guided missile for short-range engagements and matches or exceeds that of current-generation AIM-9 Sidewinders. Derby's "no escape" envelope is similar to the maximum range of the Python 4, from which it is derived. [/SIZE][/FONT]
[FONT=Arial,Helvetica][SIZE=-1]Ben-Hanan said Derby employs subcomponents and other technology from the Python 4, including the warhead and proximity fuse. Python's rocket motor was also adapted with "a little bit more energy" for Derby's beyond-visual-range profile. The missile can be fired from the same rail launcher used for the Python 4 or be adapted to other launchers. Derby has a diameter of 16 cm. (6.3 in.), is 362 cm. (12 ft.) long and weighs 118 kg. (260 lb.). [/SIZE][/FONT]

[SIZE=+3]New Beyond Visual Range Active Radar Seeker for Derby Air-to-Air Missile[/SIZE]
[FONT=Arial,Helvetica][SIZE=-1]Paris Air Show, June 2001 - A new beyond visual range (BVR) radar seeker, which was developed by Israel Aircraft Industries MBT Division, has been incorporated into Rafaels Derby air-to-air missile.[/SIZE][/FONT]
[FONT=Arial,Helvetica][SIZE=-1]This seeker is the newest component in MBTs line of advanced seekers for guided missiles. [/SIZE][/FONT]
[FONT=Arial,Helvetica][SIZE=-1]The seeker for the Derby missile is a state of the art active radar seeker for all weather, all aspect air-to-air missiles. Advanced seeker performance enables engagement of several targets from short ranges to BVR with autonomous search, acquisition and tracking airborne targets, as well as look down capability. [/SIZE][/FONT]
[FONT=Arial,Helvetica][SIZE=-1]Two seeker modes of operation are available and provide the Derby missile with excellent operational flexibility: [/SIZE][/FONT]
[FONT=Arial,Helvetica][SIZE=-1]- Lock On After Launch (LOAL) optimized for medium range targets. [/SIZE][/FONT]
[FONT=Arial,Helvetica][SIZE=-1]- Lock On Before Launch (LOBL) allowing superior performance at short range. [/SIZE][/FONT]
[FONT=Arial,Helvetica][SIZE=-1]The seekers advanced Electronic Counter Counter Measure (ECCM) capability is programmable and can be modified to the customers requirements and new threats. [/SIZE][/FONT]
[FONT=Arial,Helvetica][SIZE=-1]The seeker for the Derby missile employs advanced signal processing, is lightweight and has low power consumption. It is now operational following extensive testing and firings of the Derby missile.[/SIZE][/FONT]
