India has been offered the Stryker armoured fighting vehicle (AFV) by the United States in an effort to strengthen its deterrent against China. During the early talks about co-development, India raised worries about Stryker’s current engine, which it saw as not being suitable for use in high-altitude areas.

According to sources, the 350 horsepower Caterpillar C7 engine powering the current Stryker may not be as effective at high-altitude regions where thin air can cause engines to lose 30–40% of their power. The engine would be put under additional strain because the air defence system variant that India was offered would require the APC to carry a heavy load.

In response to these worries, the United States has extended an offer to India for an updated Stryker vehicle that is fitted with the Advanced Combat Engine (ACE) manufactured by Cummins. With 750 horsepower and cutting-edge opposed-piston technology, this engine outperforms the current one in terms of power density and heat rejection.

The United States has recently granted India authorization to receive a 1000hp variant of the ACE for its Light Tank programme, thereby showcasing its commitment to fulfilling India’s unique needs. The US offer isn’t the only one competing for the Indian Army’s armoured vehicle contract. Tata and Mahindra’s Wheeled Armoured Platform (WHAP), which was built by DRDO, is also out there.

Ultimately, the Stryker’s improved engine offer and the WHAP’s strong local competition demonstrate the US and India’s developing strategic partnership and their mutual goal in preserving regional security.
