3,986 more between FY2021 and FY2024), 140 for the Air Force, and 22 for the Navy. Other FY 2020 budget activities included US$4.8 million for engineering and manufacturing development. In March 2019, it was reported that Army's FY2020 budget request included proposed cuts to pay for modernization priorities, with one of those proposed cuts being the JLTV. It was reported that over the coming five years the service would spend US$800 million less on the JLTV program than initially expected; this potentially resulting in the purchase of 1,900 fewer vehicles. As of May 2019, the service had not changed its approved acquisition objective of 49,099 JLTVs. On 1 July 2020, Oshkosh stated that over 7,500 JLTVs had been delivered to the U.S. Army, U.S. Marine Corps, U.S. Air Force, and U.S. Navy since the production contract was awarded in 2015. This order brought the total of JLTVs ordered for US forces to date to 15,052. In September 2020 a Justification and Approval (J&A) for up to an additional 6,262 JLTVs sole source from Oshkosh was granted, the original notice (W56HZV-15-C-0095-P00282) published on 30 June 2020. This award will enable continued JLTV production, industry arguing successfully that it required up to 33 months with the JLTV TDP package to be able to respond to the A2 JLTV RfP. The up to 6,262 JLTVs approved will technically be delivered under a separate second JLTV contract, but the original contract costings and timelines and remain. Final orders must be placed in November 2023, with deliveries permitted until late 2025, but expected to conclude mid-2025. Permissible total orders under the original JLTV award were 16,901 JLTVs. When the U.S. Army unveiled its fiscal year 2021 (FY 2021) budget request in February 2020, supporting budget documents detailed plans for the "competitive follow on contract [JLTV] award" in FY 2022. It was disclosed that the service wants to reduce its JLTV buy by US$201.6 million over the coming years, but retaining a 40,099 procurement objective. Two years of JLTV production cuts, in FY 2020 and FY 2021, will now extend the full operational capability timeline out by three years until FY 2042. On 17 June 2020, Oshkosh announced the company had been awarded a $61.8M contract modification to increase available trailer options under the current JLTV Family of Vehicles contract from 32 to 3,541. The JLTV-T (JLTV - Trailer) was designed as an integral part of
