Cummins Advanced Combat Engine (ACE), an opposed-piston 1,000 hp engine,is to be demonstrated at Camp Grayling, Michigan, on 27 October, during a US Army Ground Vehicle Systems Center (GVSC)-sponsored event, Dion Anglin, the company's defence market director, told Janes on 10 October at the annual Association of the United States Army (AUSA) 2022 convention in Washington, DC.
ACE is a GVSC-funded programme to create a modular, scalable diesel engine that can power a smaller combat platform similar to the Bradley infantry fighting vehicle up to the most power-intensive platform, the Abrams main battle tank, Anglin said.
The army awarded Cummins an USD87 million contract in July 2021 to complete ACE's development. That ‘other transaction authority' contract built upon a competitive multiyear GVSC effort to develop new powertrain technology. “The OTA allows for transitioning the new technology into the next generation of vehicle programmesahead of the programmes' launch dates,” Cummins said in a statement.

Aero Vodochody AS has delivered its first batch of L-39NG trainer and light-attack aircraft to the Vietnam People's Air Force (VPAF), with remaining deliveries expected to be completed in 2024.
Vietnam ordered 12 L-39NG aircraft in February 2021. Filip Gunnar Kulštrunk, executive vice-president and chief commercial officer of Aero, told Janes that deliveries began in the fourth quarter of 2023 and that “the first batch of aircraft is now in [Vietnam]. We're going to be following up through to the end of this year. Most of this year is filled up with these delivery schedules”.
Kulštrunk offered his comments during the 2024 Singapore Airshow, which is being held from 20 to 25 February.

The Congressional Budget Office (CBO) released its regular 10-year budget and economic report on 7 February, projecting growing deficits, public debt, and costs attributable to an ageing population while revenue remains largely the same by 2034.
The CBO emphasised that its forecasts, based on legislation enacted through 3 January 2024 and economic data as of 5 December 2023, assume current laws on taxes and spending remain generally unchanged.
This budget deficit is anticipated to increase from USD1.6 trillion in fiscal year (FY) 2024 to USD2.6 trillion in FY 2034, or from 5.6% of GDP in FY 2024 to 6.1% of GDP in FY 2034, significantly larger than the 3.7% average over the past 50 years, the CBO said.
The deficit projections are smaller than in the CBO's May 2023 report due to a USD2.3 trillion reduction in discretionary spending over the 10-year period from the combination of the Fiscal Responsibility Act (FRA), which was signed into law on 3 June 2023, and the Further Continuing Appropriations and Other Extensions Act of 2024.

The deliveries of Defence Research and Development Organisation's (DRDO's) Arjun Mk 1A main battle tanks (MBTs) to the Indian Army will experience a delay because of an engine shortage, a DRDO official told Janes on 20 February.
The Indian Army ordered 118 Arjun Mk 1A MBTs worth INR75.23 billion (USD907 million) in September 2021, with deliveries of the initial batch scheduled for 2024 and the final batch in 2027.
However, because of a delay in the delivery of engines from German company MTU, the delivery of tanks to the Indian Army will be delayed as well, the DRDO official said.
The tanks were planned to be produced with German MTU MB 838 Ka-501 V10 liquid-cooled turbocharged diesel engines, but MTU requires at least four more years to initiate the production of the engines for Arjun tanks, the official added.
MTU had not responded to Janes request for comment regarding the reason for the delay in engine delivery at the time of publication.
