Tesla CEO Elon Musk has announced the company’s semi-truck won’t be revealed until November 16.

According to Musk, the delay is so the company can focus resources to fixing Model 3 production bottlenecks, as well as increasing battery production for Puerto Rico and other affected areas from recent hurricanes. The semi-truck was originally set to be revealed on October 26 and recently a photo leaked showing what is likely Tesla’s semi-truck on a trailer at the Inyokern Airport, which is about 150 miles from Tesla’s Design Center.

Earlier this month, Tesla revealed it managed to only deliver 220 Model 3 units in the last quarter, but promised the company understands what needs to be fixed in the production process. It makes sense that Tesla would want to make Model 3 production a priority over revealing its semi-truck, especially since there are so many pre-orders for the Model 3.

Musk has also been eager in assisting Puerto Rico with its energy crisis as a result of Hurricane Maria, saying he could rebuild Puerto Rico’s energy grid.
