Description
The R-27ER (and its export version R-27ER1), known as Izdelie 470-1E (Product 470-1E) or by its NATO codename AA-10 Alamo-C is a Soviet Semi-Active Radar Homing (SARH) missile first introduced in Update "Apex Predators". During the development of K-27 (later R-27R), engineers have also planned for an engine and seeker upgrade for the R series missile; however the improvements of 9-B-1101K seeker and new RDTT-300E rocket engine would still need further refinement until 1990, where the extended range missile entered service with VVS/PVO alongside with its thermal-seeker variant, R-27ET(1) which both have also been exported to multiple foreign customers.

General info
| Missile characteristics | |
|---|---|
| Mass | 350 kg |
| Guidance | SARH+IOG+DL |
| Signal | CW |
| Lock range | 25 km |
| Launch range | 100 km |
| Maximum speed | 5.8 M |
| Maximum overload | 35 G |
| Missile guidance time | 60 secs |
| Explosive mass | 24 kg TNTe |
Effective damage
The high-explosive mass usually destroys any aircraft if hit directly. It is hard to dodge as well, since it is very fast, thus the target has very little time to react.
Comparison with analogues
The R-27ER is considered to be the single best SARH missile in the game. It is incredibly fast especially at higher altitudes and maneuvers really well. The closest SARH equivalent to this missile are AIM-7F/M Sparrows, and this missile outclasses them in pretty much every way. Its practical range is almost comparable to the AIM-54 Phoenix while being much harder to evade.
Thanks to it being much faster than its counterparts, it is possible to win a missile joust against an enemy AIM-7/Super-530 type of missiles even when fired later than them.
Usage in battles
Since the missile is a long-range BVR weapon, it is best used in a range of 20-50 km. Before firing the missile off, the player should also climb to a higher altitude than the target and exceed Mach 1, as this will provide the missile more speed when being fired.
Pros and cons
Pros:
- Incredibly fast
- Ability to relock a target after firing and losing lock while maneuvering accordingly when the lock is lost
- Very manoeuvrable
- Large explosive mass
- Very long range especially when fired up at high altitudes
Cons:
- Requires carrier aircraft to guide it in all the way to impact, giving stable lock tone to the target
- The radars it is attached to isn't exactly the best in terms of pure power
- May have a hard time tracking at close ranges since it's too fast
History
See also: R-27R#History
During the initial development of K-27, the predecessor, there would be an "energy" variant for the Su-27 interceptors in PVO (and later, VVS) service with new RDTT-300E rocket motor, revised missile logic and new radar-homing seeker for the K-27E variant. The development of 9-B-1101K seeker actually began way before in 1976 by the future OAO Agat; after the technological difficulties have been addressed by the decade of 1980s, the new R-27ER entered VVS service in 1990 alongside with its thermal-seeker variant R-27ET, as well as exporting to different customers since late-1990s with the suffix "1" (R-27ER1 in this case).
