The United States Postal Service's attempt to replace its aging fleet of delivery vans with a more efficient model is going to take longer than anticipated. Originally, the USPS was to accept the first of its new Next Generation Delivery Vehicles by December of this year. But that has been pushed back until June 2024 at the earliest, according to court documents.

The quest to replace the US Postal Service's aging and increasingly dangerous Grumman LLVs began in 2015. After several years of evaluation, in 2021 the USPS announced it had arrived at a winner—a rather odd-looking van with something of a duckbill, designed by defense contractor Oshkosh. The USPS said it wanted to order between 50,000-165,000 NGDVs over a 10-year period, with an initial contract of $485 million.
