Tesla Semi is now used to move Tesla vehicles - discovered with a Model X.

It looks like Tesla Semi is using it to transport some cargo again, and some interesting, this time: a current Tesla Model X.

About a year ago, Elon Musk announced that Tesla Semi had begun its first cargo journey with battery packs from Gigafactory 1 to the Fremont factory.

While Tesla Semi prototypes have been spotted with trailers from time to time, it is not clear if freight has been moved since the first test run.

Now it looks like it could move cargo again.

Jerome Guillen, President of Tesla Automotive and Vice President of Truck, shared on LinkedIn a picture of a Model X loaded on a car transporter trailer attached to a prototype of Tesla Semi today:

The executive added the title "Aircraft Carrier," which is probably a joke about the Model X, which looks like it's flying with Falcon Wing doors open.

It's the first time we've seen Tesla Semi with a trailer for car transporters.

Interestingly, Musk announced last year that Tesla had started building its own car transporter due to an "extreme shortage", especially during the quarterly delivery as the delivery of Model 3 increased

Several months later, Tesla announced that it was buying forwarding companies to increase its delivery capacity.

Tesla has collected a lot of orders for its electric truck, but the company has always said that it would be an important user of Tesla Semi itself as part of its supply chain and sales activities.

The company has claimed that Tesla Semi will significantly increase its operating costs by using cheap electricity.

Forwarders using electric vehicles could use the difference to improve their margins or lower their prices.

In theory, using Tesla on the trucks could reduce transportation costs, which Musk sometimes called "gigantic" - for example, between Fremont Factory and Gigafactory 1.
