Prototypes and preseries are not part of the series production and are not operated by the AIr Force

- It were 7 units of pre-serial production of Su-34 that seems not counted. The total number would be 114 and 136 for the number of ordered units.
- There are 10 units of pre-serial production of Su-57 that seems not counted.
- The first unit of the Tu-160 modernized seems delivered.
- It was also a contract for 3 Yak-152 to be delivered in 2017. Not sure if delivered still.
- There are 3 units of Diamond DA-42 that seems included but must pass tests still in 2018, then the aircraft would not be formally addopted still.
- It seems to be also a first contract for the delivery of 3 Mi-38. Still seems not delivered.
In the case of "Su-34" (T-10B), the first 4 were prototypes that were not Su-34. In fact the first was only a modificated Su-27UB
The frst 4 were decomisioned and stored. Now two "pre series" continues in use operated by Sukhoy for the developement of Su-34M. After that will be retired.
There are not any Su-57 now , just T-50 , are used in the industrial program, the production starts with the first serial airplanes that will contract the Air Force
The first Tu-160M2 is not finished, will be in trials until the program is ready (new engines, etc...) and will continue in KAPO until the Tu-160M2 is ready for start the service in the airforce
I mean the first unit of the modified Tu-160 is fliying, would be also in this cathegory of prototypes and pre-serial aircrafts.
Would not be the same case of the 3 Diamond DA42? The article that confirmed its production said they must be tested in 2018. If rejected in the tests the contract would be cancelled.
Habitually in the case of the auxiliary aircrafts designed by Russian companies, the prototypes and pre-serial production are property of the companies that design and build them.
But Im not sure in the case of the combat aircrafts. Are not also these pre-serial units ordered and payed by the Russian Armed Forces? Are not the Russian Armed Forces owners of them? I have been thinking a military aircraft project born in the companies would die in the design stage without approval and order of prototypes from the Russian Armed Forces.
Tu-160 does not need prototypes as is a old Project of 80´s
The new Tu-160 is in trials at Kazan plant.
For become a Tu-160M2 a long way is necesary (new hardware and software , and new engines)
When completed as Tu-160M2 probably will be based in the training center of Long Range Aviation or in Akhtubisnk
Yak-152 and DA-42 are civil airplanes and also are very cheap airplanes
In the case of DA-42 , is form Austria and is a Project of more 15 years ago. The prototypes were in Austia in 2002. Russian Air Force it is neither the first nor the only customer.
Russia only purchases the airplanes as if you buy a car. You can drive one car before to buy, and later sign the contract and pay.
The Company can lend several airplanes for test and after the acceptance by Air Force , will be introduced in the airforce
For the moment the only airplane saw in Russia , was in the production plant in the last days of 2017
About the Yak-152, the first you can do is translate and read correctly the exact words in the news for understand what is happening:
https://bmpd.livejournal.com/3062222.htmlThe Irkutsk Aviation Plant will produce two prototype Yak-152 for flight tests and two (airframes) for fatigue and static tests.
In September 2015, Deputy Defense Minister Yury Borisov announced that the VKS intend to purchase 150 Yak-152, developed in the Yakovlev Design Bureau for initial training of pilots. Production of aircraft will be carried out by the Irkutsk Aviation Plant, and he and Yakovlev Design Bureau are members of Irkut Corporation"intend to purchase" is a different thing that "to sign a contract"
with the available informatin in bmpd , I cannot suppose the contract have been signed already, for the moment the progarm is in development
However, some western media ensure that the contract is already signed and the aircraft received by the Air Force units The first Yak-152 with the onboard number "01/201" took off on September 29, 2016.
At MAKS-2017 Drach announced that the Yak-152 will begin state tests in the fall of 2017.
The Yak-152 is a new training aircraft for the Russian Air Force. Two Yak-152s were shown at the MAKS-2017 airshow - a plane with a number "01/201", painted gray, took part in the flight program, and the aircraft numbered "02", in a red-white-yellow coloring was shown at a static display and did not go into the air until the end of the cabin. A few more aircraft are in production in accordance with the contract for conducting research and development on the subject "Bird-BBC"
This means several more airplanes will be built for test (pre-series = final prototypes with the exact configuration wanted by customer) that will be operated for the builder.
When development program is completed by the manofacturer, the supply contract
will be signed and the serial aircraft will be produced and introduced in the air force units
