An improved Japanese Type 81 SAM System with multiple vehicles is coming in the Leviathans major update for Japan!
Tan-SAM kai: An SPAA (SAM) for Japan at Rank VIII
At a glance:
- One fire control vehicle and two launchers!
- Two types of missiles: ARH and IR
- High speed
- Very large in size, with no armor
In 1966, the Technical Research and Development Institute (TRDI) began developing a new short-range anti-aircraft missile system. After lengthy tests that ended in 1979, the system was accepted into service in 1980 under the designation Type 81 (Tan-SAM or SAM-1). It was based on the chassis of Isuzu Type 73 trucks and included two launchers with missiles and a control vehicle with a radar. In 1987, a modernized variant of the SAM-1B with an improved jam-resistant IR seeker made an appearance.
In 1989, a further modernization of the system began, called Tan-SAM Kai (SAM-1C). The updated variant was accepted into service in 1995 and used the SKW-475 chassis, new missiles with IR and radar seekers, as well as an autonomous sighting system on the launcher.
In the 2000s, some of the old launchers were upgraded to use SAM-1C missiles. A total of about 1,800 missiles were produced, and the vehicles themselves were in service with the Ground, Air and Maritime Self-Defense Forces of Japan.
Introducing the Tan-SAM kai!
The new mechanics of Multi-Vehicle SAM Systems will significantly increase the combat capabilities of the Type 81(C) system, a familiar vehicle if you’ve progressed through the Japanese ground forces tree. Today we’re presenting a newer Tan-SAM kai system, consisting of a radar vehicle and two launchers, plus an arsenal of new missiles, one of which includes an active radar homing seeker (ARH). Let’s get right into it!
In the Leviathans major update for War Thunder, the Tan-SAM kai comes to the game using the brand-new Multi-Vehicle SAM System mechanic! It features three vehicles — a target acquisition and designation system (TADS) with a radar, and two missile launchers. This new vehicle solves one of the main problems with the Type 81 (C), which was its inability to detect air targets, thanks to the TADS vehicles. There are two types of missiles that the launchers are able to fire, including the familiar all-aspect Type 81C that has an IR head, photocontrast channel, good overloads and and jamming immunity, plus a new missile with an active radar homing head (ARH).
As we spoke about in the Multi-Vehicle SAM System blog, most of these new vehicles will be considered fully destroyed when the radar vehicle is lost — but the Tan-SAM kai is different! This is because the launcher vehicles can operate autonomously, without target designation from the radar vehicle — when the radar vehicle is destroyed or the radar has been turned off, then target designation for the ARH missiles is no longer possible. Despite this, you can still try to launch missiles towards a target in the hopes that the enemy will fall into the locking area of the homing head, as the Tan-SAM kai possess the “Maddog” ARH missile launch mode! Let us explain — when the missile is launched in the direction of a suspected enemy target, the missile may (or may not!) lock onto whoever is in the direction of flight and will go after them, including allied aircraft. Yeah, we can see how this one is going to work out! Make sure to be careful when using these missiles when you no longer have a radar vehicle or have turned off the radar.
The three vehicles that the Tan-SAM kai consists of are built on the chassis of a three-axle Isuzu Type 73 army truck. This truck has good driving abilities and can accelerate to almost 100 km/h. As you might have seen, the Tan-SAM kai is a large vehicle, making it vulnerable to attacks from the ground and air, plus there’s no real armor at all. When you spawn in, it would be a logical idea to place the vehicles at some distance from each other so that you avoid being taken out all at once.
That’s all for now! We’re waiting for the Leviathans major update to come out, and are getting ready to use Multi-Vehicle SAM Systems ourselves. Keep an eye out for more blogs and see you soon!
Please note that this vehicle’s characteristics may be changed before it is added to the game.

Comments will be premoderatednow japanese best spaa have open eyes lol
Thanks, Japan needed this vehicle like crazy.
Lowkey Silly That We Get The Multi-Vehicle System With 1 Radar + 2 Launch Vehicles While The Standard Type 81 Is Alone With No Radar Or Back-Up Vehicle At 11.7
In historical Type 81C, “Maddog” ARH missile launch mode is valid not only for ARH but also for IIRH, is there any plan to implement it?
the term maddog only applies to ARH. It means the missile comes off the rails "Husky"- seeking a lock with its own seeker (Pitbull) without having had a lock at launch.
I would have prefer the chū-sam type 03
Just to be sure : is it added to the actual Type 81 or replacing it ? I assume 1st but just wanna be certain.
Hello there, it is an entirely new vehicle that can be researched, it comes after the Type 81 (C) that is already in the game.
Isn't the Radarstation supposed to be slanted to have better Vertical coverage? It has been Bugreported & forwarded aswell but even in this Devblog they didn't change it
It's beautiful.
it's funny that the tech tree upgrade is just step 1: type81c step 2: type 81c (2x)
great addition but why choosing the type11 instead of the this ? would have been more comparable to all the other AA no ? Also, what is the firing range ?
