The characteristics of AAM-4 include the following.
Range extension
Realization of LOAL (Lock On After Launch) by inertial guidance with intermediate command and active radar homing.
Increased combustion time with dual thrust rocket motor (rocket motor that changes combustion pattern in two stages).
Increasing the capacity of rocket motors by downsizing onboard equipment.
Adoption of a navigation method that applies a flight method with the least energy loss.
Lower resistance of the fuselage.
Improved destruction performance
Adoption of a directional warhead (a warhead that allows the deflection of explosive power by controlling the explosion point).
Increased dispersion density of warhead fragments.
Adoption of active radar (4-quadrant active radio wave) fuse.
Unleashing ability, ability to deal with multiple targets simultaneously
Initial/intermediate guidance equipped with a command receiving device.
Equipped with a ring laser gyro (FOG: Fiber Optic Gyro).
Improving ECCM ability and clutter removal ability
Elimination of interfering signal components by employing high-speed arithmetic processing equipment.
A special modulation method that is resistant to radio interference is used in the RF transmission system of the active radar seeker, command transmitter/receiver, and active radar fuse.
Improvedmobility
Adopts rear wing steering system using electric servo actuators.
others
Reducing prices by applying COTS (Commercial Off-The-Shelf technology).
Safety is ensured by the use of PBX (Plastic Bonded Explosive) warheads.
Adoption of a high-power semiconductor transmitter for the transmitter (AMRAAM uses a TWT (traveling wave tube))"
XF-2A/F-2A did use American stuff like AIM-9Ls and sparrows but they mainly focus on additions like AAM-3 for early versions and AAM-4 and AAM-5 varients for late versions.
F-15Js however are fully compatible with AIM-120s and also the typical AIM-9L and sparrows BUT they also use the others i mentioned.
So it really depends when gaijin wants to add these missiles. AAM-3 is the closest right now.
Video showing launches of the AAM-5 not sure which version. Nothing crazy for the most part except near the end with the last launch which seems to be tracking a target behind the F-15J or to the side of it.
According to ATLA they tested a new ship borne version of the Rail gun! If im not mistaken this prototype is a world’s first on a ship. The ship was not named but it’s likely the JS Asuka which is used for experiments. Hopefully more news will be announced.
A small post about the supposedly “3 times wider off-boresigth” capabilities of the AAM-3 over the AIM-9L.
First and foremost the AIM-9L has a 45° gimbal. But that does not mean the AAM-3 has 3*45° gimbal = 135° gimbal
Indeed its litteraly imposible to have +90° gimbal when you look at picture of the seeker position.
What i think it means is a “3 times bigger circle of what the missile see”.
At 2km:
The gimbal of the AIM-9L is 45° meaning it’ll see a circle with a radius of 1657m at 2km. The area of this circle will be PI*(1657)^2= 8.6 * 10^6 meter square
The gimbal of the AAM-3 currently modelled is 60° meaning it’ll see a circle with a radius of 2309m at 2km . The area of this circle will be 1.67 * 10^7 meter quare.
If we do 1.67 * 10^7/8.6 * 10^6 we get a 1.94, meaning the circle the missile see at 2km is 2 times bigger.
If we do the same at 3km:
Aim-9L: radius =2485 m, Area = 1.9410^7
AAM-3: radius = 3464 m, Area = 3.7710^7
3.77/1.94=1.94
If we do the same at 5km:
Aim-9L: radius =4142 m, Area = 5.3910^7
AAM-3: radius = 5773 m, Area = 1.0410^8
1.04 * 10^8/5.39 * 10^7= 1.92
So from calculus with the 60° HOBS of the AAM-3 actually implemented in game we only get a “2 times bigger circle”.
If we want a “3 times bigger circle” then:
For 2km, area of the AAM-3 circle = 3*area of the AIM-9L circle → area of the AAM-3 circle = 2.58 * 10^7 m^2.
→ radius of the circle = 2866m → gimbal of the seeker = 71.25°.
It’s a lot better than the 45° you can find on the 9L but still a lot more reasonnable than the 135° gimbal.
*I just used random distance values (ie 2km for the gimbal calculacion) because the relation between the size of the circle of both missile didn’t changed mutch with the distance so i simplified it and assumed it was proportional.
