made system has been installed. The

Elektroavtomatika NSTs-T was developed

for the Yak-130 combat trainer, but it has

now been adapted for  ghter aircraft

and the NSTs-T-04 variant features in

the Su-35.

Other smaller re nements for the Su-35

include relocation of two (of the six) decoy

dispensers in the rear boom between the

engines from the top to the underside in

the later aircraft. The tip of the boom has

been coated with a rubber-like material,

probably radar-absorbent. The windshield

de-icing system has been changed from

electrical to an alcohol sprayer, and the

grids protecting the bottom of the air

intakes have been altered too.

Defensive and offensive

The Su-35 has a very elaborate self-

defense system. The L150 (SPO-23) Pastel

radar-warning system is widely used on

Russian aircraft. The version in the Su-35

added millimeter-wave receiver modules

for improved accuracy.

The SOER (Sistema Optiko-Elektronnoi

Razvedki, electro-optical reconnaissance

system) warning system includes six

infra-red SOAR (Stantsiya Obnaruzheniya

Atakuyushchikh Raket) missile approach

warning sensors: one forward-looking

mounted near the IRST; one aft-looking,

mounted on the fuselage spine behind the
