The '''''Project 04260''''' class, NATA reporting name: '''Claire''', is a class of long-range diesel-electric attack submarines in service of the [[Itayana Maritime Force]]. It was originally designed in late 2000s as the bigger of the two domestic submarine designs. The class had a protracted development history, being plagued by financial problems, lack of necessary equipment and overly ambitious requirements, necessitating outside help to be completed. Nonetheless, six submarines of the initial '''Project 04261''' entered the operational service in late 2010s. Additional four boats of the related '''Project 04262''' are under construction as per 2022.
The '''A6''' (NATA reporting name: '''Bison-T''') is a type of strategic bomber in service of the [[Itayana Solar Air Fleet]] (ISAF) and [[Itayana Navy|Itayana Naval Aviation Division]] (INAD). It was derived from the Velikoslavian {{wp|Myasishchev M-4|3M strategic bomber}} design (ISAF designation: '''A4''') procured during 2000s to provide the nascent Solar Air Fleet with long-range capabilities. The aircraft was developed with technical assistance of [[Oxidentale Jet Works]] consortium and incorporates several improvements over the baseline design, including using composite materials and new avionics.  


===Development===
First flown in 2009 an entering service in 2012, it is one of the largest aircraft in service of the Solar Air Fleet and the largest aircraft domestically assembled by [[Itayana]] yet. Existing reports indicate the production is underway on the Aircraft Plant No.98 at a slow rate. Estimates vary as to how many aircraft are in service, though no more than 20 are assumed to be operational at present.
Unlike with most of the [[Itayana Maritime Force]] projects, the '''Project 04260''' has a relatively known design history coming from the interviews of its lead designers and analysis of the open-source intelligence.


The decision to create an ocean-going diesel-electric boat came from the [[Admiralty of IMF]] in 2002. The design requirements called for a boat capable of operating in Salacian and Oorupaqi oceans in anti-shipping and anti-submarine role. Diesel-electric propulsion was maintained as it was deemed that the economy and industry of Itayana would not be able to handle a fleet of nuclear submarines. Other limiting factors were the size of the slipways and available industrial equipment on the [[Shipbuilding Plant No. 143]], the only facility that could build ocean-going submarines in Itayana. The design process correlated with industrial re-armament of the shipbulding plant. It was complicated by progressively more and more ambitious requirements regarding armament, sonars, signatures and automation; nevertheless, it was completed by 2009 and the first two boats were laid down in early 2010.
==Operation and intended role==
'''A6''' bombers serve in the [[9th Air Wing]] of the [[Itayana Solar Air Fleet|ISAF]]. It is reported that the Solar Air Fleet maintains its strategic bomber force for stand-off missile capabilities, but available footage of various exercises suggest several other roles, including control of ground-launched cruise missiles and penetration operations. If proven correct, A6 bombers mark a major improvement of the ISAF capabilities compared to the older {{wp|Myasishchev M-4|A4 bombers}} due to their advanced avionics and operational employment. However, penetration operations put expensive airframes at risk and it is deemed unlikely that they will be conducted.


Construction process involved expensive contracts from several countries such as [[Sante Reze]], [[Orun Redisus]], [[Alanahr]], [[Zacapican]] and [[Elatia]]. The first pair of boats was launched in 2015, the acceptance trials lasted for two years and were finished in 2017. The boats received numerical indexes instead of names in line with the IMF naming conventions.
The most prominent appearance of the 9th Air Wing so far was an air parade during the state visit of [[Indóre II of Orun Redisus]] in 2020, on which eight A6 were observed among other planes of the formation.


===Design===
The [[105th Air Wing]] of the [[Itayana Navy|INAD]] employs a naval derivative of the A6 bomber, designated '''K6''' and distinguished by additional data links to integrate it with ships of the Itayana Navy, and possibly having extended combat range. One plane was observed on joint naval exercises with [[Zacapican]] in 2019 and three were present at the similar exercises with [[Sante Reze]] in 2020. This suggests a very low number of aircraft in service and that the Solar Air Fleet has a priority in receiving A6 airframes.
The '''Project 04260''' is a large ocean-going submarine desgined for anti-shipping and anti-submarine operations.


The submarine is powered by diesel-electric transmission and a waterjet. While the lack of primary sources on the waterjet suggests its domestic origins, available information indicates that different submarines use different engines from several manufacturers from [[Zacapican]] and [[Alanahr]]. Despite that, it is stated that submarines are capable of acheiving 15 knots surfaced and 25 knots underwater. The submarine has a crew of 45, suggesting high degrees of automation, and is designed for endurance of 90 days.
==Observed Variants==
Two variants of the aircraft were observed so far:
* '''A6'''. The baseline version, serving as a strategic bomber and missile carrier.  
* '''K6'''. The naval aviation derivative with additional data links and sensors.  


The submarine's primary armament is four 650mm torpedo tubes. The choice of the larger torpedoes was dictated by torpedo design bureaus and justified with sgnificantly larger warhead, improved physical signatures and more sophisticated guidance systems. The submarine is also armed with two 324mm internal torpedo tubes and four external 324mm torpedo launchers. Information on either 324mm or 650mm torpedoes of Itayana is sparse at best, but it is stated that the submarine is intended to carry 16 650mm and 20 324mm reloads.
==Specifications==


Project 04260 posssess a sophisticated set of electronic equipment. For underwater detection the submarines possess a sphericalbow sonar, six flank arrays, a towed array, two arrays on the sail and several antennas of wake detection system. Surface control is provided with an X-band air search radar and an electronic warfare suite. All sensors are integrated around the ''White Whale'' suite, stated to allow high degrees of automation, reducing the need for the crew.

The A6 (NATA reporting name: Bison-T) is a type of strategic bomber in service of the Itayana Solar Air Fleet (ISAF) and Itayana Naval Aviation Division (INAD). It was derived from the Velikoslavian 3M strategic bomber design (ISAF designation: A4) procured during 2000s to provide the nascent Solar Air Fleet with long-range capabilities. The aircraft was developed with technical assistance of Oxidentale Jet Works consortium and incorporates several improvements over the baseline design, including using composite materials and new avionics.

First flown in 2009 an entering service in 2012, it is one of the largest aircraft in service of the Solar Air Fleet and the largest aircraft domestically assembled by Itayana yet. Existing reports indicate the production is underway on the Aircraft Plant No.98 at a slow rate. Estimates vary as to how many aircraft are in service, though no more than 20 are assumed to be operational at present.

Operation and intended role

A6 bombers serve in the 9th Air Wing of the ISAF. It is reported that the Solar Air Fleet maintains its strategic bomber force for stand-off missile capabilities, but available footage of various exercises suggest several other roles, including control of ground-launched cruise missiles and penetration operations. If proven correct, A6 bombers mark a major improvement of the ISAF capabilities compared to the older A4 bombers due to their advanced avionics and operational employment. However, penetration operations put expensive airframes at risk and it is deemed unlikely that they will be conducted.

The most prominent appearance of the 9th Air Wing so far was an air parade during the state visit of Indóre II of Orun Redisus in 2020, on which eight A6 were observed among other planes of the formation.

The 105th Air Wing of the INAD employs a naval derivative of the A6 bomber, designated K6 and distinguished by additional data links to integrate it with ships of the Itayana Navy, and possibly having extended combat range. One plane was observed on joint naval exercises with Zacapican in 2019 and three were present at the similar exercises with Sante Reze in 2020. This suggests a very low number of aircraft in service and that the Solar Air Fleet has a priority in receiving A6 airframes.
