Description
The 1RL144 also known by its NATO reporting name Hot Shot is a Soviet ground based target detection and tracking radar suite. In game it is found on the 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.
