The 1RL33 is capable of both scanning for targets and locking onto targets, however it does not offer "Track While Scan" (TWS) capability, this means that the radar must cease scanning in order to lock onto a target. As a result of this if a target is locked onto then all other radar blips will stop updating and be removed from the display within a few seconds. Upon a target lock being lost the radar will revert to scanning. When the radar is locked onto a target it will stop sweeping and instead point directly towards the target, following it as the target moves.

The radar has a "Line of Sight (LoS) scan" mod. In this mode the radar dish is locked in place facing the front of the turret, as such it will only detect targets within a very narrow azimuth range, relative to the front of the turret, however elevation scanning angles remain unchanged. In LoS mode the radar (and thus the turret) need to be directly facing a target in order to detect it, once a target has been detected it can be locked onto in the normal manner and the radar will automatically follow it; once a lock is lost the radar will revert to LoS mode and face the front of the turret. The benefits of operating the radar in LoS mode are that as the radar is not emitting in all directions you will not alert enemy aircraft equipped with radar detectors to your presence unless you aim directly at them.

The default scanning mode of the 1RL33 is to scan a 90 degree arc. It is possible to switch the radar into scanning a full 360 degree, although due to the incredibly slow scanning speed this option is rarely desirable.

The F-16A is very strong in a dogfight due to its excellent TWR and energy retention, its highly manoeuvrable and can easily reach its top speed even when climbing. Its so good that you will often experience the effects of the G-limit, so when making a sharp turn keep that in mind.

<!-- ''Describe the tactics of playing in the aircraft, the features of using aircraft in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them.

−
The F-16A can be a powerful fighter with multiple playstyles, one option being simply rushing straight into battle. Players that plan to stay low and accelerate straight into action will be satisfied with the F-16's low-altitude performance and radar. A mixed countermeasure loadout (1 flare, 1 chaff) is recommended because it allows 30 countermeasure drops against radar or IR missiles. In order to be prepared for matches that may extend longer than usual, select the 30-minute fuel option in conjunction with the 300-gallon drop tank. The F-16 consumes a lot of fuel on afterburner, so it's essential to use it wisely unless the max fuel amount is selected.
 
−
 
 
−
With the [[AIM-9L Sidewinder|AIM-9L Sidewinders]], players can carry up to 6 AIM-9Ls. If a player finds themselves above the fight, it will be effortless to fire off missiles at distracted enemies and score kills quickly. AIM-9Ls are very strong from the rear aspect and require hard defending from the opponent to evade successfully.
 
−
 
 
−
The F-16 is very strong in a dogfight due to its excellent TWR and energy retention. Before entering a dogfight, however, it's critical to be at the correct speed. The F-16 has a very wide turning circle at high speeds, so make sure to stay around 800-850 km/h (497-528 mph) when entering a dogfight.
 
−
 
 
−
'''Countering the [[MiG-29]]'''
 
−
 
 
−
The MiG-29 is a very versatile and capable fighter and will be one of the most common enemies you will face. However, like many planes, it's possible to counter it. It's one of the fastest jets on the deck (~1,550 km/h, 963 mph) and has access to a helmet-mounted sight, which allows the player to lock the missile in the direction of the pilot's view rather than just along the nose of the aircraft. This allows for off-bore missile launches which can be a threat. It's important to be on the lookout all the time for any missile launches, whether it be an [[R-60M]] or an [[R-27T]].
 
  
−
Avoid entering a high-speed rate-fight with a MiG-29 at all costs as the MiG-29 is much more manoeuvrable at high speeds, however at low speed the F-16 is able to outturn the MiG-29 thanks to its better low speed handling.  
+
Compared to other search and tracking radars the 1RL33 has a decent range of 20 km for detection and 16 km for tracking. It is the only search radar primarily designed for scanning a small sector, instead of 360 degrees; as such it has an incredibly slow scanning speed. Being a combined search and tracking radar like the [[Marconi S 400]] the 1RL33 lacks track while scan capability, however like the Marconi it can also track targets through a full 360 degrees.
  
−
The MiG-29 at high altitude can be dangerous if the opponent utilizes [[R-27ER|R-27ERs]]. The R-27ER has superb range, acceleration, and manoeuvrability. To counter this, stay on the lookout for MiG-29s and R-27ERs and be prepared to go into a notch position and drop chaff. The R-27ER burns for 9 seconds which allows it to be spotted for a long time before the motor burns out.

== History ==
 
== History ==
−
Two projects from Northrop and General Dynamics reached the final of the LWF (LightWeight Fighter) competition to create a new light fighter for the US Air Force. In January 1975, the winner of the competition was the YF-16, developed by General Dynamics. Intense testing continued after the launch of the F-16A fighter into series, and was completed only in 1978. The new generation fighter was designed for Mach 2 speeds and was able to perform maneuvers at 9G overloads, which was even higher than the requirements declared in the competition. The F-16A took her full-scale baptism of fire in service with the Israeli Air Force over Lebanon in the early 80s. The jet fighters were also used against ground targets during Operation Desert Storm. Consistently improving, the F-16A fighters are being produced and modernized to this day. In addition to the United States, a number of foreign countries have become operators of the F-16A Fighting Falcon fighters, including Belgium, Israel, Pakistan, Italy, Indonesia and others. Fighters are produced both domestically and under license.

The 1RL33, also known as the RPK-2 "Tobol" was a soviet radar developed in the 1950s for use on the [[ZSU-23-4]] SPAA vehicle. The radar reportedly suffered from high levels of ground clutter (false returns on the radar display) under certain operating conditions, but offered good resilience against radar countermeasures.
 +
 
 +
The NATO reporting name for the radar system was "Gun Dish".

Description

The 1RL33 / RPK-2 atop the turret of a ZSU-23-4

The 1RL33 or RPK-2 "Tobol" is a Soviet ground-based target detection and tracking radar.

Vehicles equipped with this radar

General info / usage

The 1RL33 is capable of both scanning for targets and locking onto targets, however it does not offer "Track While Scan" (TWS) capability, this means that the radar must cease scanning in order to lock onto a target. As a result of this if a target is locked onto then all other radar blips will stop updating and be removed from the display within a few seconds. Upon a target lock being lost the radar will revert to scanning. When the radar is locked onto a target it will stop sweeping and instead point directly towards the target, following it as the target moves.

The radar has a "Line of Sight (LoS) scan" mod. In this mode the radar dish is locked in place facing the front of the turret, as such it will only detect targets within a very narrow azimuth range, relative to the front of the turret, however elevation scanning angles remain unchanged. In LoS mode the radar (and thus the turret) need to be directly facing a target in order to detect it, once a target has been detected it can be locked onto in the normal manner and the radar will automatically follow it; once a lock is lost the radar will revert to LoS mode and face the front of the turret. The benefits of operating the radar in LoS mode are that as the radar is not emitting in all directions you will not alert enemy aircraft equipped with radar detectors to your presence unless you aim directly at them.

The default scanning mode of the 1RL33 is to scan a 90 degree arc. It is possible to switch the radar into scanning a full 360 degree, although due to the incredibly slow scanning speed this option is rarely desirable.

Comparison with analogues

Compared to other search and tracking radars the 1RL33 has a decent range of 20 km for detection and 16 km for tracking. It is the only search radar primarily designed for scanning a small sector, instead of 360 degrees; as such it has an incredibly slow scanning speed. Being a combined search and tracking radar like the Marconi S 400 the 1RL33 lacks track while scan capability, however like the Marconi it can also track targets through a full 360 degrees.

Pros and cons

Pros:

  • Decent range
  • Can track targets through a full 360 degrees
  • Good minimum range
  • Radar shuts down immediately when turned off and stows away only marginally taller than the turret

Cons:

  • Slow scanning speed
  • Slow scanning speed makes 360° scan mode of limited use
  • Lacks "Track While Scan" capability

History

The 1RL33, also known as the RPK-2 "Tobol" was a soviet radar developed in the 1950s for use on the ZSU-23-4 SPAA vehicle. The radar reportedly suffered from high levels of ground clutter (false returns on the radar display) under certain operating conditions, but offered good resilience against radar countermeasures.

The NATO reporting name for the radar system was "Gun Dish".
