Elon Musk bought a Gulfstream G550 jet in August 2020 and another in September 2021.
The jets, which Musk likely purchased pre-owned, are the latest addition to his fleet of four private planes.
A new Gulfstream G550 costs $62 million; preowned G550s retail from $14 million.
It's no secret that Musk is a big fan of Gulfstream jets — he owns three of them.
In addition to the G650ER he acquired in 2016, the Tesla billionaire also owns two G550 planes, FAA records show. Musk also owns a Dassault 900B, the first jet he ever purchased.
Musk's first G550 jet was registered to Falcon Landing LLC in August 2020, a shell company with ties to Space X, aircraft registration records show. In September 2021, he bought another jet, which was also registered to the shell company.
Musk's jets are under the registration numbers N272BG and N502SX, according to the FAA registry. The jets were previously registered to Contrail Aviation LLC and Wells Fargo Bank, indicating that Musk purchased the planes pre-owned.
Gulfstream started manufacturing the G550 in the early 2000s. The US aviation company no longer makes the G550, a company spokesperson told Insider.
In an interview with Chris Anderson at the TED Conference in April, Musk said he lives a frugal lifestyle but makes an "exception" for his fleet of private jets.
"I mean, the one exception is the plane, but if I don't use the plane, then I have less hours to work," Musk said.
Musk and Tesla did not immediately reply to Insider's requests for comment.
A new Gulfstream G550 jet will set you back a hefty $62 million.
A virtual tour of the plane shows four individual seats in the forward cabin. Each of the seats has a storage area and a control panel. Stowed on the side of the plane are foldable wooden tables.
The mid-cabin has a "club-four"-style dining area with an extendable table and two pairs of seats facing each other. The plane has 14 windows.
The divan-style sofas can be converted into a sleeping space.
Retrofitted G550 jets are equipped with Gulfstream's Cabin Management System (GCMS), a system that allows passengers to control lighting, temperature, speakers, and window shades using a touchscreen, according to Business Jet Traveler.
The rear cabin can be designed with one or two divan sofas that can be converted into a bed. The lavatory and baggage area are located at the tail end of the plane, the tour shows.
