Are the plan upgrade icons ( elite mortar,diving bell, etc.) only available as you progress the story line along to a certain point or is accomplishment of a certain number of related tasks the trigger? Thanks.

The plan upgrades become available when you find them. Most are located on dive locations, so you can't get them prior to acquiring the diving bell.
