I-16 Type 6 by N.N.Polikarpov

b/w 80k Type 6 from Ever Changing Page of Roy Cochrun. Interestingly, the windshield installed appears to be a rear cockpit windshield from late UTI-4 trainer

In late 1937 the I-16 Type 5 was replaced in production line by better powered Type 6 with improved M-25A engine. It also had fixed smaller single-peace windscreen to comply with pilots suggestions. More advanced gunsight PAK-1 replaced OP-1 tube. Gun camera became more common than in the Type 5, and trim tab was added to the flaps on late production models (retrofitted on service aircraft too).

For winter operation fixed skis could be employed. Before arrival of the Il-2 many I-16 Type 6 were used for ground attack, carrying 4 or 6 RS-82 unguided rockets.

Served with Spanish Republican airforce since May 21, 1937 (first delivery), reassigned to training units when better armed Type 10 was delivered. Some early Type 6 served in China (differed by old OP-1 gunsight).

During the World War II few of Type 6 were captured by Finnish Army, only one was airworthy. It had a fixed ski undercarriage, replaced lated by wheels. Used in combat.

About 700 built.

Here is a question about I-16 Type 6 at Spain, submitted by Mr.Henri San Benito:

On several Spanish books and revues like "Miranda and Mercado World Aviation in Spain" you can see and you can read that some I-16 type 6 sent to Spain had installed the Forward Sliding Canopy. But in the Squadron/signal publication "Polikarpov Fighters" you can read that the I-16 type 6 never had installed the cockpit canopy. (removed from type 5 following the request of the Soviet pilots) .

My question is if you know that on the very first I-16 type 6 production serie the sliding cockpit Canopy had been installed, and these airplanes had been sent to Spain. Or never the Type 6 had been installed the Cocpit canopy.
