The '''Grumman Long Life Vehicle''' ('''LLV''') is an American light transport truck model designed as a [[mail truck]] for the [[United States Postal Service]], which has been its primary user since it first entered service in 1986, 39 years ago. It was also used by [[Canada Post]]. The LLV uses a chassis built by [[General Motors]] based on its [[Chevrolet S-10 Blazer|Chevrolet S-10]] with an aluminum body built by [[Grumman]].

In 2021, after a long competition, the USPS announced it had awarded a $6&nbsp;billion contract to [[Oshkosh Corporation|Oshkosh Defense]] to produce the [[Next Generation Delivery Vehicle]], which will replace the LLV. In February 2023, the USPS announced the purchase of 9,250 each of stock [[Ford Transit#E-Transit|Ford E-Transit vans]] and [[Stellantis]] gasoline-powered vans.<ref>{{Cite web |last=Gitlin |first=Jonathan M. |date=2023-05-02 |title=New USPS electric vans delayed until mid-2024, according to court docs |url=https://arstechnica.com/cars/2023/05/new-usps-electric-vans-delayed-until-mid-2024-according-to-court-docs/ |access-date=2023-07-01 |website=Ars Technica |language=en-us |quote=With the bespoke NGDV delayed, the USPS has ordered 9,250 Ford E-Transits… first of those E-Transits won't arrive until the end of this year}}</ref> {{As of|May 2023}}, the first custom NGDVs were scheduled to enter service in June 2024, nine months after the original October 2023 target date.<ref>{{Cite news |last=Shepardson |first=David |date=2023-05-02 |title=U.S. Postal Service next-generation delivery vehicles delayed to mid-2024 |language=en |work=Reuters |url=https://www.reuters.com/world/us/us-postal-service-next-generation-delivery-vehicles-delayed-mid-2024-2023-05-02/ |access-date=2023-07-01}}</ref>
