A
Soviet Union SA-4 TEL
A
transporter erector launcher (TEL) is a
missile vehicle with an integrated
prime mover (tractor unit) that can carry, elevate to firing position and launch one or more
missiles. Such vehicles exist for both
surface-to-air missiles and
surface-to-surface missiles. Early such missiles were launched from fixed sites and had to be loaded onto trucks for transport, making them more vulnerable to attack since once they were spotted by the enemy they could not easily be relocated, and if they were it often took hours or even days to prepare them for launch once they reached their new site.
The term can also refer to support structures used to transport a
rocket launch vehicle horizontally from an assembly facility to a nearby fixed
launch pad where it is raised vertical for launch. This system is used, for example, by
SpaceX for its
Falcon rockets.
A
transporter erector launcher and radar (TELAR) is the same as a TEL but also incorporates part or all of the radar system necessary for firing the
surface-to-air missile(s). Such vehicles have the capability of being autonomous, greatly enhancing their effectiveness. With this type of system each vehicle can fight regardless of the state or presence of support vehicles. The TEL or TELAR may have a rotating turntable that it can use to aim the missiles. The vehicle may have to turn to aim the missiles or they may fire straight up.
Conversely, a
transporter launcher and radar (TLAR) is the same as a TELAR without the erector capability, because the missile in question is transported in the launch-ready position. An example is the
9K330 Tor, which mounts a
Vertical Launching System-style block of SAMs.
Usually a number of TELs and TELARs are linked to one
command post vehicle (CP or CPV). They may use target information from
Target acquisition, designation and guidance radar (TADAGR) or, simply,
TAR.
