Based on Anonymous commentsof August 11-12, 2017 I have compiled TABLE 1 below. For an overview of the Soryu program see TABLE 2 below that:
TABLE 2 - Overvie of SORYU (& Oyashio) Programs as at August 15, 2017
Soryu Mark IIs are likely to cost more than US$91 million = 10 Billion (B) Yen (¥) than Soryu Mark Is due to new:
- batteries, LIBs (replacing LABs+Stirling AIP) and diesel generator sets (gensets) for greater power
generation, and
- sonar systems new sonars for improved detection of the enemy and for better submerged
navigation-by-sonar
navigation-by-sonar
TABLE 1
Item/Submarine Type | Soryu Mark I | Soryu Mark II | Comments |
SS order number | 16SS – 26SS | 27SS and 28SS | See Soryu Table below |
Batteries + AIP (where applicable) | LABs + Stirling AIP | NCA LIBs[1] | |
Cost of batteries/Soryu in Billion Yen (¥***B) [2] | LABs ¥1.44B | NCA-LIBs ¥8.3B | LIBs per Soryu almost 6 times costs of LABs |
Battery cost/performance [3] | 4.5 (for 576 LABs fitted) | 5.4 (for 480 LIBs fitted) | |
Specific energy (Wh/kg) [4] | 40-60 | 240 | LIBs have 4-6 x the specific energy of LABs |
Budgeted costs per Soryu in Billion Yen [5] | 26SS ¥51.7B (FY2014) | 27SS ¥64.4B (FY2015) 28SS ¥63.6B (FY2016) | MK IIs ¥12-13B more expensive than MK Is |
Extra cost for in MK IIs [6] | genset about ¥2B higher sonars ¥3-4B higher |
[1] Soryu Mark IIs will likely be equipped with (NCA LIBs) Lithium nickel cobalt aluminium oxide ( LiNiCoAlO2 ) made by GS Yuasa.
[2] According to the Japanese Ministry of Defense’s Acquisition, Technology & Logistics Agency (ATLA) the costs of LABs and NCA-LIBs are reported to be 1.44 ¥B and 8.3 ¥B, respectively. This makes NCA-LIBs just under 6 times more expensive than LABs for each Soryu sub. But, in terms of cost/performance (see [3]), NCA-LIBs are not overly expensive.
[3] More precisely, price ratio of LAB to NCA-LIB is 4.5 and 5.4 for 576 and 480 LIBs in Soryu Mark II, respectively.
[4] Specific energy of NCA-LIBs are 240 Wh/kg and LABs are 40-60 Wh/kg. The specific energy of NCA-LIBs are 4 to 6 times that of LABs nearly the same as the above mentioned price raitio.
[5] Significant portions of the ¥12-13B cost of Soryu Mark IIs over Soryu Mark Is include...
[6] ...about ¥2B higher for the new gensets and ¥3-4B higher for new sonars. This suggests major changes in gensets and sonars for the Soryu Mark IIs.
