The '''1RL144''' also known by its NATO reporting name '''Hot Shot''' is a Soviet [[SPAA radars|ground based target detection and tracking radar suite]]. In game it is found on the [[ZPRK 2S6|ZPRK 2S6 Tunguska]]. The radar suite consists of a search radar mounted on-top of the Tunguska's turret, at the rear, and a tracking radar mounted on the front of the turret.

==General info / usage==


Consisting of both a search radar and separate tracking radar the 1RL144 offers a form of Track While Scan (TWS) capability (true TWS requires a single radar to perform both actions). The search radar provide full 360 degree coverage, while the tracking radar is limited to tracking targets within a 180 degree arc from the front of the turret. The search radar has only one scanning mode and is can be folded when not in use.

===Comparison with analogues===


Compared to other search and tracking radars the 1RL144 has a decent range of 20 km for detection and 16 km for tracking. Being two separate radars it allows a target to be tracked, while still scanning for new targets. The tracking search radar has a good minimum relative speed of only 36 km/h. The tracking radar has slightly narrower azimuth tracking angle than the Gepard's radar (±90° instead of ±100°).

===Pros and cons===


'''Pros:'''
* Decent Range
* Can still scan while tracking a target
* Better than average minimum relative speed
* Radar can be folded when not in use to decrease vehicle size

'''Cons:'''
* Slightly worse azimuth tracking angles than some other radars
* Delay of approximately 3 seconds to power up radar
* Only one scanning mode

== History ==


The 1RL144 (NATO reporting name "Hot Shot") was a Soviet radar system developed in the 1970s as part of the 1A27 radar complex, to serve as the fire control system for the Tunguska anti-aircraft system. As well as the search and tracking radars which made up the 1RL144, the 1A27 also featured a control computer and angle measurement system. Later models of the Tunguska featured a new radar complex with an "Identification Friend or Foe" (IFF) system, which allowed the radar to identify which radar returns were from friendly aircraft, and which were from enemy aircraft.
