The Kasta 2E (NATO: Flat Face E, alternative name Casta 2E) is a modern Russian radar system.

The development of the Kasta 2E surveillance radars was initiated in the former Soviet Union. Its primary objective is to overcome deficiencies or to satisfy the demand in low-level surveillance.

The Kasta 2E1 system uses two antennas and consists of two vehicles:

The Kasta 2E2 system uses one antenna and consists of three vehicles:

Both radar types can be triggered with either equal or opposed phases. The both antenna types can optionally be mounted on a standard 50 m pylon. This arrangement causes a displacement of the radar horizon which in turn increases the detection altitude up to 6 km at a distance of 150 km.

Rapier (missile) Surface-to-air missile

Rapier is a surface-to-air missile developed for the British Army to replace their towed Bofors 40/L70 anti-aircraft guns. The system is unusual as it uses a manual optical guidance system, sending guidance commands to the missile in flight over a radio link. This results in a high level of accuracy, therefore a large warhead is not required.

Railroad car Vehicle used for carrying cargo or passengers on rail transport system

A railroad car, railcar, railway wagon, railway carriage, railway truck, railwagon, railcarriage or railtruck, also called a train car, train wagon, train carriage or train truck, is a vehicle used for the carrying of cargo or passengers on a rail transport system. Such cars, when coupled together and hauled by one or more locomotives, form a train. Alternatively, some passenger cars are self-propelled in which case they may be either single railcars or make up multiple units.

PAVE PAWS Early warning radar

PAVE PAWS is an elaborate Cold War early warning radar and computer system developed in 1980 to "detect and characterize a sea-launched ballistic missile attack against the United States". With the first solid-state phased array deployed, the system at the perimeter of the contiguous United States used a pair of Raytheon AN/FPS-115 radar sets at each site as part of the United States Space Surveillance Network. One system was sold to Taiwan and is still in service.

AN/TPQ-36 Firefinder radar

Hughes AN/TPQ-36 Firefinder weapon locating system is a mobile radar system developed in the mid-late 1970s by Hughes Aircraft Company and manufactured by Northrop Grumman and ThalesRaytheonSystems, achieving initial operational capability in May, 1982. The system is a "weapon-locating radar", designed to detect and track incoming mortar, artillery and rocket fire to determine the point of origin for counterbattery fire. It is currently in service at battalion and higher levels in the United States Army, United States Marine Corps and Australian Army. Also Turkish Army, Portugal and Ukrainian Army are among the users.

AN/TPQ-37 Firefinder radar

Hughes AN/TPQ-37 Firefinder Weapon Locating System is a mobile radar system developed in the late 1970s by Hughes Aircraft Company, achieving Initial Operational Capability in 1980 and full deployment in 1984. Currently manufactured by ThalesRaytheonSystems, the system is a long-range version of “weapon-locating radar,” designed to detect and track incoming artillery and rocket fire to determine the point of origin for counter-battery fire. It is currently in service at brigade and higher levels in the United States Army and by other countries. The radar is trailer-mounted and towed by a 2⅓-ton truck. A typical AN/TPQ-37 system consists of the Antenna-Transceiver Group, Command Shelter and 60 kW Generator.

Giraffe radar

The Saab Giraffe Radar is a family of land and naval two- or three-dimensional G/H-band passive electronically scanned array radar-based surveillance and air defense command and control systems tailored for operations with medium- and Short Range Air Defense (SHORAD) missile or gun systems or for use as gap-fillers in a larger air defense system. The radar gets its name from the distinctive folding mast which when deployed allows the radar to see over nearby terrain features such as trees, extending its effective range against low-level air targets. The first systems were produced in 1977. By 2007, some 450 units of all types are reported as having been delivered.

Type 95 SPAAA Self-propelled anti-aircraft gun/missile system

The Type 95 is a Chinese self-propelled anti-aircraft vehicle. It is armed with four 25 mm caliber cannons and optionally four fire-and-forget QW-2 infrared homing missiles. It was first displayed publicly at the Beijing Military Parade in 1999. Earlier in development the system was designated Type 90-II and Type 90-III.

The British Armed Forces operates a wide range of communications and information systems. Some of these are specialised military systems, while others are procured off-the-shelf. They fall into three main categories: satellite ground terminals, terrestrial trunk communications systems, and combat net radio systems. Every part of the Army and the uses combat net radio, but only the Royal Corps of Signals and the Royal Air Force operates trunk systems and multi-channel satellite communications.

The Reeves AN/MSQ-51 Aerial Target Control Central (ATCC) was a combination radar/computer/communications system developed 1961-3 for United States Navy "aerial target out-of-sight control". In addition to the "Target Control System AN/SRW-4D" with radios and "Antenna Assemblies for Target Control and Communications ", the ATCC included acquisition/surveillance and tracking radars, a Mark X IFF/SIF, and an analog computer. The ATCC's automatic tracking radar was derived from the Western Electric M-33 gun laying radar and could process double-pulse 9340-9370 MHz beacon returns from transponders up to 400,000 yd away from the AN/MSQ-51 transmitting 9215-9285 MHz radar pulses. If an ATCC was equipped with a "Telemetry Receiving Station", IRIG channels 5-14 could also be received from QF-9G and Q-2C unmanned aerial vehicles. Other ATCC-controlled drones included the QF-9F, KDA-1, KDA-4, KDB-1 and KD2R-5. For "RF communications " to command the drone was a "Collins Radio Co.
