In the framework of military-technical forum "Army-2019" design Bureau "Vympel" demonstrated its new development – a missile "air-air" which exceeds in its parameters the existing missiles of this class.

"Product 180" is a new missile received index K-77M, which will be initially installed on su-57, and in the future may go for export abroad.

And though the rocket received index K-77M, but it has nothing to do with the missile K-77. The rocket is produced with a new aerodynamic scheme with X-shaped wings that reduces drag and as a consequence increased range.

Rocket in addition to the main wing (2 in diagram below) also added a stationary aerodynamic surface (4) before "driving" (3), which allowed to solve the main problem of all long-range missiles "air-air", namely the ability to maneuver at subsonic speeds. For example, the famous American missile AIM-120 and its recent modernization the AIM-120D have not been able to maneuver at speeds of less than 1200 km/h (while trying to maneuver increased angle of attack, and the rocket began to disintegrate.)

Also the missile is equipped with a double-pulse solid-propellant engine, which allowes high-altitude maneuvering and enables a range of up to 192 kilometers.

In addition, the missile is equipped with inertial navigation system and active radar homing head.

All these changes make the new missile K-77M a truly unique and a real formidable weapon.

Experts pay attention that apparently the Russian defense Ministry are very serious about the project su-57 and to develop this fighter is really unique weapons that have no analogues in the world. We already know that the su-57 would be installed a shorter version of hypersonic missile "Kinzhal" gliding cluster bomb "Drel", and now the missile K-77M. All of these types of weapons created recently and is unique in its characteristics.

The latest development of JSC "mnii Agat"

is Designed primarily for advanced missiles "air-air" medium-range missiles, in particular, for the R-77M.

Serial production of the missile already starts, in accordance with the contract signed, the Ministry of defense during the forum Army-2019.

According to the developers, the GOS is also suitable for rockets of class "air-surface".

Having an antenna diameter of only 100 mm, seeker can detect targets with

RCS of 0.003 sq. m at a distance of over 2 km
with RCS of 0.1 sq m (rocket "air-Air" or stealth fighter) - 5 km
with RCS of 5 sq m (conventional fighter) - more than 12 km

Available frequency bands of operation - Ki and Ka.

Weight of GOS is noticeably smaller than its predecessor 9B-1103М (for missiles R-77-1 and RVV-SD) - weight 3.5 kg vs 5.7 kg, 230 mm length 300 mm and diameter 100 mm vs. 150 mm, with comparable characteristics.

However, the main feature of GOS is electronic beam steering antennas and, as a consequence, much more rapid scanning of the airspace in comparison to all predecessors that will be surely helpful for the tasks of missile defense of the carrier, and also in conditions of active electronic countermeasures by the enemy. In creating the AESA seeker for this was also attended by Fazotron-NIIR and NIIP Tikhomirov.

Air-to-air guided missile

The RVV-MD air-to-air guided missile is designed to destroy air targets (fighters, attack aircraft, bombers, helicopters and military transport aircraft) from any direction, day or night, against the earth background, and in a heavy ECM environment.

The RVV-MD is a short-range dogfight missile with all-aspect passive infrared homing (a two-band IR seeker) and combined gas/aerodynamic control.

Fuze type: radar. Warhead type: rod.

Looking at the range figures RCS of 0.003 sq. m at a distance of over 2 km for Ka band seekers.

I think they have opted for higher frequency MMW seeker of 40 GHz Ka band and focused on Anti-Jamming/Burn through capability , Target Imaging with Ka band and all weather capability over Longer range for seeker.

Using K or Ku band as in R-77 might have its limitations in an era where AC carry DRFM jammers and stand off jamming available , Ka band should also be good against LO Target. and using AESA can provide faster Scan Rates and lower side lobes with perhaps lower power needed.

This would also mean R-77M would depend on AC main radar for LR tracking , Guidance and MC updates.

The RVV-BD carries dual seeker of X/Ku Band , R-77 etc carries Ku band seeker and the one for R-77M is a new AESA seeker with Ka Band

Would be interesting if that turns out to be the K-77M.
This missile seems to be about 2.2m long and has a diameter is about 25cms. If we compare it to R-77-2 which is 3.71m long and has 20cms diameter, the volume for both comes out to be 0.108cbm & 0.116cbm respectively. But larger diamater allows the seeker to be reduced in length and also have a bigger antenna. The difference is just 0.008cbm between the two. If you remember I had suggested that even the range of Astra can be increased by just increasing its diameter by 4cms to make it 20cms and providing for dual pulse motor.

Actually, there is no R-77-2, there's only the 3.6m long R-77 (Izdeliye 170) and 3.7m long R-77-1 (Izdeliye 170-1). K-77M is called Izdeliye 180. So it's really 0.108, 0.113 and 0.116 cbm. The only 4m long missile I know of is China's PL-15.

If that schematic posted is right, what's really impressive is that each half of the main bay can carry 4 missiles each, that's 16 missiles internally. Even if it's just 2 each, that's still 8 missiles.

The two main bays could carry maximum of three R-77s each and two on side bays. this increases the load out to eight in main bays and two in side bays.
With these missiles, it will get to the internal bay load out of MSA. But if MSA had to use these missiles, the internal bay load out of MSA will rise to 12 missiles.

I'm guessing MSA's main bay is 5+m long and around 1.5m wide. This will allow it to carry 4 missiles side by side, with an equal number of missiles in tandem, 8 in total.

If we take into consideration the shortened nose cone at front of this new missile, there may not be any difference in the fuel volume or it may actually be more. The R-77-1 has a longer nose cone and a smaller motor, but this new missile will have bigger motor giving it a much higher initial thrust and consequentially higher speed in shorter burn time.
 
I'm guessing MSA's main bay is 5+m long and around 1.5m wide. This will allow it to carry 4 missiles side by side, with an equal number of missiles in tandem, 8 in total.
The main bays are 4.5m long, 0.7m deep and 1.2m wide. The side bays are 4m long, 0.5m deep and 0.8m wide. The main bay allows carriage of 2xmeteor and 2xASRAAM in staggard manner. The two side bays can carry 2xMeteor each. I have kept the design LO and not gone for VLO to provide for 2xASRAAM on wingtips. The wingtips of the design can be easily replaced to achieve VLO design on line flying.
