how does the Pe-2 fare?
Wikipedia shows this (credited to Yefim Gordon Soviet combat aircraft of the Second World War):
TypeAverage number of missions flown before loss
Su-280
Pe-254
Il-2 (two seat)26
A-2019
Il-2 (single seat)13
I messed up the formatting lol, but interestingly it appears that the Su-2 actually did the best. We should keep in mind though that we don't know what year this was for, or what other metric was being used.
 
Interesting facts from the report:
As a teenager, I talked to a Soviet pilot who fought on a Boston. I didn't ask about the technical details, but I remember well that the pilot spoke only enthusiastically about his aircraft. He said he was very lucky - the Boston was reliable, could withstand significant damage, and was very comfortable for the crew. In general, the figures seem somewhat strange to me, perhaps because the Bostons were mainly involved in the fiercest battles - in this particular case, the interpretation of the statistics is far from obvious.
 
These figures do not allow us to draw any general conclusions about the quality of the aircraft. The variability in losses was enormous - much depended on the experience of the pilots and the strength of the enemy, so the small number of Su-2s with experienced crews could well have suffered fewer losses. I repeat, the number of sorties per loss varied greatly during the war, and it is only possible to compare figures from the same section of the front during the same period. But even with a correct comparison within the same aviation division, losses in the Su-2 regiments were lower than in the Pe-2 regiments - I explained the reason for this above. Overall, the Su-2 was perhaps underestimated, while I consider the Pe-2 to be another major mistake by the Soviet leadership - it was an extremely difficult aircraft for pilots to master and even to fly - especially on landing. Moreover, it had a relatively small bomb load.
 
So how did the I-16 actually perform as fighter in WW II (Sept 1939 on)?
How did the I-16 perform as a ground attack plane in WW II?

Most of the WW II planes had the M-62 or M-63 engines. Only a few of these had 20mm cannon. Most had four 7.62mm guns, two synchronized and two unsynchronized. The Soviet 7.62mm machine gun have a very high rate of fire. It is possible that some carried bombs, the usual underwing load was six RS-82 rockets. However the RS-82 was not exactly a powerhouse. Destructive power was probably close to an 81-82mm mortar shell.
The last I-16s traded the wing guns for a 12.7mm mg in the lower engine cowl.
The I-16s lacked firepower for ground attack so you needed more missions/sorties to cause the same amount of damage.
 
There were several I-16 variants with a pair of 20mm ShVak in the wings. I don't know how often they were or weren't actually fitted but some definitely were

I am curious from which source you obtained this information. The distribution by type for 1941 is only available for naval aviation fighters, where most of the I-16s were indeed equipped with M-62/-63 engines (215 versus 129). I have not seen such data for the Air Force I-16s. Most of the I-16s produced were equipped with M-25 engines, and the most common type was the UTI-4 (type 15) trainer.
Only a few of these had 20mm cannon.
715 built. Not that little.

That's right, but even with its limited effectiveness as a ground attack aircraft, the I-16 could perform many more missions than the Il-2. The I-16 could not replace a proper ground attack aircraft, but there are many examples of successful attacks on ground targets using the RS.
 
I used some reasoning.
The Soviets switched from the M-25s to the M-62 series in 1939, roughly 2 years before the Germans invaded.
There is no doubt that there were still M-25 powered planes in inventory but how many of the older ones were in front line service?
How many of the older ones were still on the books but awaiting new or repaired engines or other parts?
Using UTI-4 (type 15) trainers in combat was not going to end well and they are not a good indicator of the I-16s actual combat capabilities.
The fixed landing gear on most of the trainers was going to hurt performance even if they only flew with one pilot and faired over the 2nd cockpit.

In this particular case, I fully admit that your assumption is reasonable. But when studying the history of Soviet aviation, you constantly encounter situations where extrapolations and reasonable assumptions do not work due to the absurd features of the Soviet system. Therefore, knowledge of exact figures is preferable. For example, I cannot say from general considerations whether the distribution by type was the same or similar for the I-16 in the naval and army aviation.

I will only note that the I-16 type 5 was often encountered in 1942, and pilots claimed that they were not afraid to engage the 109s in combat with this type. At the same time, they were instructed to attack bombers preferably on a head-on course.
They could be used as a source of spare parts when repairing I-16s with M-25s.
 
If I was standing next to political officer with a loaded pistol in his holster I would be inclined to say things that would keep me alive at least until the next day.

Granted not all factories ended production at the same time but the type 10 started to replace the type 5 in 1937 (?).
So what is the definition of "often encountered" when discussing 5-6 year old planes in the Soviet Union in 1942?
On Mission out of 10 flown? 1 mission out of 20 flown? 1 Mission out of 50 Flown?

Have you decided that the discussion lacks silly clichés that have nothing to do with reality? It was about interviews in the 1990s and 2000s.

Firstly, type 10 was produced from February 1938, while type 5 was produced until March 1938. Secondly, the difference between these types in terms of flight characteristics is minimal. Thirdly, some of the Type 5 aircraft were upgraded - about 200 aircraft received additional PV-1 or ShKAS guns. There was a program to upgrade ALL I-16 Type 5 aircraft of the late production series (after the 32nd), but the factory did not have the required capacity.

It is possible that about half of all I-16s in 1941 were equipped with M-25s, but it is unlikely that anyone can say exactly how many there were in 1942. The difference between types 5 and 10 is minimal, so I don't see any point in distinguishing between them too much.

I suspect that aircraft equipped with the M-25 were even more reliable than those equipped with the M-62/M-63, and it was easier to find spare parts for them.
 
Soviet pilots disliked the cannon versions of the I-16, calling them "irons" because of their reduced maneuverability due to increased weight. The increased firepower did not compensate for the deterioration in flight characteristics.
 
One thing I'm curious about, given the apparent agility of the I-16 (high roll rate and tight turning circle, with fairly good power) I wonder why they did not seem to do so well against A5M, Ki-27 and of course, the Ki-43 and A6M in China etc.

The agility seems to be comparable to all of these aircraft, though I assume the Ki-43 and A6M are more powerful.

This would explain Boris' willingness to switch to the Hurricane the moment it became available to the Soviets.
I've wondered this too. When the A6M was first operationally tested in 1940 (A6M2 Model 11 specifically) it practically mopped the floor with the I-16 and I-15. They both had the same large flaps for good low speed mobility idea so I wonder what the issue was. Maybe the better stability of the A6M combined with the mostly better pilot skills of Japan? (Not that China didn't have good pilots, of course.)
 
An extremely rearward center of gravity on the I-16 improves maneuverability, but greatly reduces stability. It is a fundamentally unbalanced aircraft. A pilot needs to be very experienced to take advantage of the I-16's strong points. And the VVS RKKA had a serious shortage of experienced pilots

From the interviews, it seemed like they loathed the Hurricane. Golodnikov sure didn't rate it.

Seemingly with A5M and Ki-27 too, not to mention Ki-43 needless to say.
