RAF Lossiemouth will continue to play a key role in an independent Scotland, Moray MP Angus Robertson has said.
However, details of aircraft and personnel at the base have still to be revealed.
And the SNP's new defence policy has been attacked by political rivals.
An updated policy was presented this week by Mr Robertson, SNP Westminster leader and defence spokesman.
The policy includes continued membership of the North Atlantic Treaty Organisation, although subject to the withdrawal of Trident from Scotland.
The policy will be debated at the SNP conference in October.
Mr Robertson said there would be an increased budget for conventional defence in Scotland compared to the UK with a professional defence force of 15,000 regular and 5,000 reserve personnel.
All military bases will remain in operation with Faslane becoming a major conventional naval base and home to Joint Forces Headquarters. Lossiemouth and Leuchars will both operate air force capabilities.
"In the run-up to the independence referendum it is important to lay out SNP priorities for international relations, security and defence policy and these proposals show the clear advantages of making decisions in Scotland," he said.
"With agreement on the withdrawal of Trident and retaining the important role of the UN, Scotland can continue working with neighbours and allies within NATO."
An independent Scottish government led by the SNP will commit to an annual defence and security budget of £2.5bn, an annual increase of more than £500m on recent UK levels of defence spending in Scotland but nearly £1bn less than Scottish taxpayers currently contribute to UK defence spending.
The Scottish defence and peacekeeping forces will initially be equipped with Scotland’s share of current assets including ocean going vessels, fast jets for domestic air patrol duties, transport aircraft and helicopters as well as army vehicles, artillery and air defence systems.
Mr Robertson said joint procurement will be pursued with the rest of the UK and other allies as well as shared conventional basing, training and logistics arrangements.
However, Shadow Defence Secretary Jim Murphy said: "This raises more questions than it answers and has more to do with the referendum than the defence of our country.
"It is a really clumsy attempt at an SNP u-turn which has landed them back where they started: totally confused about defence.
"The first responsibility of any government is to keep its people safe. This should have been the first policy the SNP worked out, not the last.
"The SNP are still busking it, making it up as they go along.
"They still haven't answered the basic question of why would Scotland want to separate from the Royal Air Force, British Army and Royal Navy," he added.
