Pete's Comment: If Thailand bought used Ming subs from China Thailand might receive them in 2019 - depending on Chinese modifications. Used Kilos are harder to estimate. If Thailand prefered 2 or 3 new submarines costs would be much higher and involve:
- significant lead times for negotiating, ordering and building submarines - generally around 6 years for a new customer like Thailand
- in the case of South Korea as a supplier a backlog of pre-existing orders might perhaps cause delays. This may mean a minimum delivery year of 2020 for Thailand to receive the first sub then add 3 years for commissioning (tests, trials and training) the sub into the Thai Navy ie. 2023.
