STRIL
Encyclopedia
STRIL is short for "Stridsledning" which means "combat management" in Swedish
. STRIL 50 (operational in the 1950s) and STRIL 60 (operational in the 1960s, 1970s and 1980s) were integrated systems for air combat
management including early warning and ground-controlled interception
. The systems depended on radar
and radio
as primary technologies but STRIL 50 was based on manual control while STRIL 60 applied the usage of early digital computer
s.
STRIL 60, designed in cooperation with Marconi, were in the very frontline of providing combat critical information to airborne aircraft, the Saab 35 Draken and Saab J32 Lansen fighter aircraft, by means of digital telemetry
links with direct presentation of target guidance data on dedicated gauges on the cockpit instrument panel. The uplink to the aircraft could resist heavy jamming and the Swedish Air Force
was first in the world to provide digital combat guidance that would remain reliable in a hostile and interfered radio environment.
Eventually, The Saab 37 Viggen aircraft system also utilized STRIL 60 but target presentation in the cockpit was then replaced by digital computer displays instead of the mechanical gauges used on the Draken.
In the 1990s, STRIL 60 was replaced by STRIL 90 which is a modern combat management system integrated with the Saab S100B Argus combat management/surveillance and SAAB JAS 39 Gripen
multi-role combat aircraft.

Ground-controlled interception
Ground-controlled interception an air defense tactic whereby one or more radar stations are linked to a command communications centre which guides interceptor aircraft to an airborne target. This tactic was pioneered during World War II by the Royal Air Force with the Luftwaffe to follow closely...
. The systems depended on radar
Radar
Radar is an object-detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. The radar dish or antenna transmits pulses of radio...

Radio
Radio is the transmission of signals through free space by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space...
