Aston Martin has long been synonymous with James Bond. The British luxury automaker first popped up in a Bond flick when Sean Connery slipped behind the wheel of a silver DB5 in 1964’s Goldfinger, and has been a steady part of the franchise all the way up to Daniel Craig retrieving his old trusty whip from MI6 at the end of 2015’s Spectre. (It was the best part of Spectre.)

But Aston Martin isn’t content with just building fancy cars for would-be Bonds. It also wants to build slick submarines for would-be Bond villains.

At this year’s Monaco Yacht Show (note to self: attend next year’s Monaco Yacht Show), the manufacturer announced it’s teaming up with Triton, a submersibles company, to work on “Project Neptune,” a private luxury submarine that combines some of Aston’s classic designs with Triton’s state-of-the-art undersea tech.

Is it completely badass and befitting of an evil, one-armed or one-eyed or one-legged bad guy? Yes. Will it also cost you in the neighborhood of $4 million? Yes.

That’s partly because Aston Martin describes the Project Neptune concept as a “super-yacht” sub, and as we’ve learned, superyachts don’t come cheap. Though the final product will undoubtedly look a lot different—that is, if it ever reaches production—you’ll apparently have the ability to plunge to the depths of the ocean, or at least 500 meters, for up to 12 hours while plotting to destroy the world, per AutoWeek

CNN says the submarine will start shipping to obscenely wealthy people by the end of next year, but in the meantime, Project Neptune is just the first of many non-automotive ideas to fall under Aston Martin’s new consulting division. According to a press release, the branch “provides design, engineering, and manufacturing services to select industries, distilling the brand’s essence into exciting new project without compromising Aston Martin’s fundamental qualities.”

Personally, I’d like to see an Aston Martin jetpack next, but then again, I’d just really like to see a jetpack, period.
