Currently the 4th line in the Japanese tech tree, the strike aircraft and light bomber line, ends at rank III with the B7A2. For the players that have it, the 3 R2Y2 variants do show up at rank V, however I am sure once there has been a replacement added to the tech tree they will be put to the side where other removed vehicles go.
Additions:
Rank IV:
Spoiler
⬠B-33
Spoiler
Czechoslovak license-produced Il-10 that we all know and love, the aircraft was imported to Indonesia from Poland around 1957-58. Registrations ranged from F-371 to F-384. The B-33 is identical to the Il-10 in all aspects except for modified fuel tanks, increasing its flight time. All aircraft in Indonesian service were eventually returned to Poland.
Cavalier Mustang II
Spoiler
A refurbished P-51 with improved performance and secondary weapons capability, I won’t go too in depth as @NFrost51 has already created a great forum suggestion on the aircraft; Cavalier Mustang II - Retired, Refurbished, Reborn
⬠B-26B Kalong
Spoiler
The last Invaders put into active service. Used extensively until 1977, 35 years since its first flight, Indonesia operated this strike aircraft during several campaigns in East Timor. The aircraft was modified to carry a variety of modernized secondary weapons including soviet made bombs and more modern rockets, making this one of the more unique of the Invader variants that could come to the game. @Indo_Pilot has already made a suggestion for this beauty: Douglas B-26B "Kalong" - "Invader's Last Hurrah in Indonesia"
Rank V:
Spoiler
⬠Il-28
Spoiler
This aircraft was operated by the AURI for 5 years before being donated to the ALRI, the naval air force branch. All pilots were trained in Czechoslovakia. Aside from a few incidents, the service life of this aircraft remained fairly uneventful. Here is a good source on the Il-28 in Indonesian service if you are curious: DEFENSE STUDIES: Mengenang Kebesaran TNI AU Lewat Pembom Ilyusin-28
⬠A-4E
Spoiler
14 of this variant were purchased from Israel in 1979, and remained in service up until 2004. These aircraft were known as “Si Bongkok”, or The Hunchback, in Indonesian service, due to the fuel hump. During service the Skyhawks participated in many military operations such as Operation Sriti Samber, Operation Seroja, Operation Oscar, and Operation Rencong Flying.

⬠OV-10F
Spoiler
An export variant of the OV-10A Bronco developed in the USA, again I won’t go too in detail as @NFrost51 has made a suggestion post on this aircraft: OV-10F Bronco: The American Wild Horse with Soviet bombs
Rank VI:
Spoiler
⬠Tu-16KS-1
Spoiler
Received in 1961, the Tu-16 was the first long range strategic bomber put into service with the Indonesian Air Force. The aircraft was part of a large purchase from the Soviet Union, including Tu-16s and MiG-21F-13s. Details of the flight route and transportation of the Tu-16 to Indonesia are not well documented in publicly available sources.
Indonesia was the first country outside of the Soviet Union to operate the Tu-16, and the USA used this to their advantage, using U-2 spy planes to get a close look at the new Soviet long range bomber.
Rank VII:
Spoiler
T-50i
Spoiler
In May of 2011, Indonesia signed a contract with South Korean aviation company KAI for 16 T-50i advanced trainers. Deliveries began in 2013, and final deliveries were made in 2014. A further 6 aircraft have been ordered since 2021, with 4 total having been delivered. Though specified as a training aircraft, the T-50i possesses modern CAS capabilities, and is a shining example of success for the rapidly expanding Korean foreign arms market, having variants exported to Indonesia, Iraq, Malaysia, The Philippines, Poland, and Thailand. With a united Korean tech tree already confirmed to be in the works, it would be a fun addition to see added in its many variants.
M-346F
Spoiler
Just a few days ago, the M-346F was selected to replace the aging Hawk 209 aircraft in Indonesian service. Not much has yet been said on this acquisition, as it stands they have not been purchased yet, but in the coming months I am sure we will see more info on this coming out.
Rank VIII:
Spoiler
⬠Su-27SK
Spoiler
Export variant of the Su-27S, nearly identical in performance to the Su-27 found in the USSR tree. The aircraft has been modified to support accommodations for air-to-ground missions.
⬠Su-27SKM
Spoiler
Derivative of the Su-27SK with an upgraded cockpit, upgraded electronic countermeasure system, and an in-flight refueling system.
⬠Rafale C F4
Spoiler
*Photo is of Rafale B F4, 2 seater variant. The Rafale C F4 is scheduled for delivery this year.
The top aircraft of this line proposal, the Rafale C F4 has seen extensive success in the export market, with one of its newest customers being the TNI AU. The battle rating of 14.7 shown in the tech tree visual is a placeholder as higher brs have not been added yet, and the F4 variant when added would likely be a higher br. For more information on this aircraft, @WreckingAres283 has done a great job breaking down all Rafale variants in their post here: Dassault Rafale - Variants, Characteristics, Armament and Performance - Part 2
⬠Su-30MK2
Spoiler
Identical to the Su-30MK2 found as a premium in the USSR tree, we suggest this be added as a premium to Japan as the Venezuelan Su-30MK2 is one of the most liked and best selling premiums, and we believe this would be a much more popular purchase over the F-2A ADTW.
⬠F-16C
Other possible additions:
Spoiler
There are many other possible additions to this tree that could be added, this is simply how we (the people who created this post) would prefer to see this sub-tree line come to the game. A more comprehensive list of all Indonesian aircraft that could be added can be found here, a post made by @NFrost51 :

This post was worked on by me, @Oversights, @galexzilla, and @Indo_Pilot over on the Japan / SK / ASEAN Research Server. Special thanks to everyone who provides information both over there and here on the Forum.
Semoga sukses, para pilot. Sampai jumpa di udara!
