Gurechaff LaGG-9 Fighter Jet

### Designed By

• Taisiya Ivanovich Gurechaff (lead designer)• AIS Gurechaff (design organisation)

The Aviatsionnaya Ispitatelnaya Stantsiya (AIS) **Gurechaff** LaGG-9 (Rossi: \_\_ Гуречап \_\_) is a supersonic, single/dual-seat, single engine, fighter jet and interceptor aircraft which was developed and manufactured by Russian aircraft company (name). It was the first Russian combat aircraft to exceed Mach 2 in horizontal flight, a feat which was achieved on (O.S.) 16 Iyun 1883 (483 A.C.) over a rough flight test over Europa.

* Canopy (cockpit front) — 6mm titanium
* Canopy (cockpit rear) — 18mm titanium

Cavitation nozzle rod protects the jet's main fuselage, and foldable air intake doors to prevent collision cascade detonation.

#### Avionics

The jet uses the SOG-122C1 fire-control system with:

* Pederev FeBO NOD-19-06 collimator reflex sight, with lock-on ability
* SP-122M3 radar datalink transciever connected to VRK B/C-scopes:
	+ Shiklop datalink
		- VRK-1165-1 B-scope for searching target azimuth and range, beacon and IFF responses
		- VRK-1165-2 C-scope for searching targets, scan pattern
		- VRK-1165-3 C-scope for tracking targets, range rate and artificial horizon line
* Voln SVO-26 RWR
* Gozrykh-5 ADF

The fire-control system uses the radar dome with:

* 1Vs21 fire-control radar, with up to 40—120km of radar scanning distance, recieves IFF responses
* TP-14Sh infrared search-and-track pod
* Voln SRVZ(M)-2 IFF transciever set

A single radio communication set is located within the cockpit for the pilot:

* 10R419 radio communication suite

#### Countermeasures

Two sets of octuple-cartridge dispensers for 16 total rounds of chaff/flare countermeasures.

* ShPK-76/85 airborne chaff-and-flare countermeasure suite; 16 rounds total
