Defence Minister Sukumpol Suwanatat wants to submit the navy's proposals to buy second-hand submarines to the cabinet next week.
However, he said he was unsure whether they will be submitted in time for the cabinet meeting on Tuesday.
The minister said a few more days are needed to discuss the proposals before they can be forwarded to the cabinet.
ACM Sukumpol said it was a race against time as Germany, which makes the submarines, has given the government until the end of the month to decide whether to buy them or not.
ACM Sukumpol says he supports the navy's position that it needs the submarines to fulfil its maritime defence missions.
