9K33 OSA [ROAF SAM System]

[Battlerating 12.0]


Thank you for buying the blueprint for the 9k33 Osa, this is a mobile spaa that is amphibious and has 6 SARH deprecated radar guided rockets that don't care about chaffs, it's good that the missiles are super accurate if they get a proper lock on. It can reach 140kph on land and about 60 kph in water, 1:1 recreation.



-Amphibious 60KPH [Do not stay still in water]
-Drag racer: 120kph in about 9 seconds.
-Climber: can climb mountains.
-Deadly: Targets under 3.5km are no more if you launch a rocket.
-Full to the brim: 6 rockets [5km max range but 3km best operational range because of the radars]
-Fuel efficient: Has enough fuel for about idk more than 2 hours.
-Fire prevention automated equipment.
-New best SAM system [Better than the Kub systems due to more missiles and better performance]

Startup

1.Engine key
2. (Optional): Turn off economic mode / turn on high speed gear / turn on high RPM gear / turn on lights / Lock turret to drive position.

Aiming turret

1. Reset radar position
2. Activate Radars
3. Activate lock on
4. Launch missile when locked (recommended range 1-3km due to deprecated radar unreliability)

How to get in

-There are 2 windows on each side jump on them [the backones may require to grab one handle then jump on the chassis [the front ones are pretty straight forward to use].
-Open the hatch, close it and get in the seat fast so it doesn't yeet you outside

How to get out

-Open hatch enter seat
-Exit seat
-Ctrl+Jump
-Close hatch

Amphibious mode

1.Activate propellers
2. Do not stay still in water if you want trim the w/s to get a constant lift from the back propellers. (because if you open hatch water will get inside though that's not such a big problem cuz there are pumps inside)




Produced by the USSR/Russia, there are many export customers for this system, including Cuba, Greece (from the former East Germany), Poland, Syria, Ecuador and Iraq.

After the Israeli invasion of Lebanon in 1982, in which Syrian air defenses were obliterated by a massive air campaign against Syrian SAM sites in the Beqaa valley, the Syrians managed to deploy Osas. At least one F-4 Phantom in a SEAD mission was shot down on July 24, 1982 by an Osa system. The WSO (back seater), Aharon Katz was killed, while the pilot, Gil Fogel, survived and was held captive by the Syrians for two years.

In late 1980s, Cuba deployed several 9K33 Osa units in southern Angola which posed a significant threat to South African air superiority at shorter ranges. The South African 61 Mechanised Battalion Group captured an intact 9K33 Osa anti-aircraft missile system on 3 October 1987 during the Battle of Cuito Cuanavale. This was the first time that such a system had ever fallen into the hands of non-Warsaw Pact forces, giving Western intelligence agencies an opportunity to examine an important Soviet-bloc weapon system.

Iraq used Osa systems during the 1991 Gulf War.

The system also saw use in the 2008 Russo-Georgian War by both the Georgian and Russian militaries.

Libyan 9K33 Osa were used, and some destroyed during the 2011 Libyan Civil War by NATO airstrikes.

The Osa was the first mobile air defense missile system incorporating its own engagement radars on a single vehicle.

All versions of the 9K33 feature all-in-one 9A33 transporter-launcher and radar vehicles which can detect, track and engage aircraft independently or with the aid of regimental surveillance radars. The six-wheeled transport vehicles BAZ-5937 are fully amphibious and air transportable. The road range is about 500 km.

The 1S51M3-2 radar system on the 9K33 Osa TELAR received the NATO codename Land Roll. It was derived from the naval 'Pop Group' radar system but is smaller since it does not require the elaborate stabilisation system. An improved system, the Osa-AKM (NATO reporting name SA-8B 'Gecko' Mod 1) was first seen in Germany in 1980. It had improvements added to the launcher configuration, carrying six missiles in ribbed containers.

The system is reported to be of the frequency-agile monopulse type. It consists of an elliptical rotating surveillance antenna mounted on top of the array, operates in H band (6 to 8 GHz) and has a 30 km acquisition range against most targets. The large pulsed J band (14.5 GHz) engagement antenna is mounted below it in the centre of the array and has a maximum tracking range of about 20 km.

Mounted on either side of the tracking radar antenna is a small J band parabolic dish antenna to track the missile. Below that is a small circular antenna which emits an I band uplink capture beam to gather the missile shortly after launch. The final antennas in the array are two small white rectangular ones, one on either side of the array mounted alongside the I band. These are used for command uplink to the missile. This twin antenna system permits the 'Land Roll' radar to control up to two missiles simultaneously against a single target.

The two missiles can be guided on different frequencies to further complicate electronic countermeasures (ECM). There is a tubular device fitted to and above the tracking radar; this is a 9Sh33 electro-optical tracker. It can be used to track the target when the main tracking radar is jammed by ECM.

A 9K33 battery comprises four 9A33B TELAR vehicles and two 9T217 transloader vehicles on BAZ-5939 chassis with reload missiles and a crane. A reload time of five minutes has been reported per TELAR.

In addition to the TELARs, each regiment is also assigned a single radar collimation vehicle 9V914 (initially on the BAZ-5938 chassis but more often found on the ZiL-131 truck). This vehicle assists in the alignment of the TELAR's radar systems, ensuring accurate target tracking and engagement.
