Japan’s Ministry of Defense (MOD) announced the Financial Year FY 2018 budget on August 31, 2017. Based on the FY 2017 and FY 2018 budgets, the SORYU & Oyashio Program Table (above) can be revised (in red) as follows.

(1) Correction of 29SS; i) “Build No” is 8128; “[the Japanese Ministry of Finance (MoF)] approved amount Yen Billions & FY” is JPY 76 (7.6*)B FY2017.

(2) Addition of 30SS; i) “Build No” is 8029?; MoF approved amount Yen Billions & FY” is JPY 71.5 (2.3*)B FY2018 (submitted).

* Figure in bracket is the first year cost, such as new equipment, and is excluded from the FY budget number. In other words, the real budgets for 29SS and 30SS are 83.6 (=76 + 7.6) and 73.8 (=71.5 + 2.3) JPY B (Billion Japanese Yen), respectively. The first year cost for both 29SS and 30SS recognises that the builders of the two submarines are different.

According to the MOD, first year costs include i) design, ii) test, iii) technical collaboration, and iv) acquisition costs. These costs exclude jigs/tools, machines and equipment. These costs are related to the first year procurement and are specially required for production. 


The first year cost of 29SS (ie. 7.6 B JPY) is much higher than 30SS (2.3 B JPY). One major cost component may be design. The design cost of 29SS is obviously higher than 30SS.

(3) For application in future 29SS-type submarine, a budget for the study of a new silent driving system has been submitted.

Research on the quiet propulsion (or silent driving?) system and hull shape are considered budgeting. The results of previous research will be applied to 29SS-type submarine. An issue remains whether 29SS type submarines can be called Soryu Mark 3 or Soryu Mark 4. A submarine class that follows the Soryus will likely be based on additional research.

Reported in the Japanese language publication SHIPS OF THE WORLD, October 2017 - the ex-commander of the submarine fleet Admiral (retired) Masao Kobayashi (photo and bio details below from Submarine Matters' records) has revealed that 29SS is an upgraded version of the Soryu, with improved LIBs, improved sonars and other performance improvements. So 29SS and 30SS can be considered Soryu Mark 3s.



 Vice Admiral Masao KOBAYASHI, JMSDF (Retired)  

Masao KOBAYASHI has performed as an adviser to Japan's National Security Council. He graduated from the Japanese Defense Academy in 1973 and commenced a career in the JMSDF submarine service. He held many posts in the submarine force.

Shore billets included Submarine Branch Head in the Ship Systems Section in the Maritime Staff Office and Operations Officer in the Fleet Submarine Force.

He has commanded TAKASHIO SS-571 (Uzushio class submarine), and was Commander of Submarine Division Two. In 2001/2 he was the Commander of Submarine Flotilla One, and was Coordinator of Exercise at sea for Pacific Reach 2002.

Masao’s last post was as Commander of the Fleet Submarine Force (2007 - 2009). He retired from the JMSDF in 2009. Vice Admiral KOBAYASHI served with distinction in the JMSDF and is well regarded as an authority in the international submariner community.

Hi Pete

According to MoD, first year cost, which includes i) design cost, ii) test cost, iii) technical collaboration cost, and iv) acquisition cost of exclusive jigs/tools, machines and equipment, is related to the first year procurement and is specially required for production.

First year cost of 29SS (7.6 B JPY) is much higher than 30SS (2.3 B JPY). One of the reasons may be design cost. Design cost of 29SS is obviously higher than 30SS.

Reseachs on quiet propulsion system and hull shape are budgeting. Result of former research will be applied in 29SS-type submarine (Soryu MK III b or MK IV?). Post Soryu may be based on result latter research.

Hi Pete

In MoD, first year cost and specication of purchasing product are two criterions for judging whether the product is new or not. In the case of new product, first year cost is usually incurred and new specification is needed. But it is not the case for 29SS where first year cost is incurred but specication is revised, suggesting that 29SS series belong to Soryu series, but are going to experience big modification.

On reseach on quiet propulsion system, low noise driving sytem and its control system is developed. Proto type system is manufactured from 2018 to 2021, and its evaluation is conduced in 2022 with total budget of 5.6 B JPY. As cost of current propulsion system is ca. 1B JPY, big improvement in performance is expect.

So, new quite driving and control system may be equipped in late 29SS series (Soryu Mark IV?).

The next China flat top is coming, 2019-2020, this time with CATOBAR. Drawings on the web show J-20 in hangar, if remotely true that is going to spell troubles for all tose F/A-18 and F-35. USN watch out.

Hi KQN

I see it more likely China would use the developed J-15* for the first few years of CATOBAR (Type 002**) carrier operations.

Using an immature J-20 with an immature 002 AND getting past the US F-35 lead may all wait till 2028 or later.
