The US Army has issued a Sources Sought Notice for major lethality improvements upgrades to the complete Stryker vehicle family.
The notice is for informational gathering purposes only and the upgrade programme is still in early planning.
The next round of upgrades is expected to bring more enhanced firepower support for infantry and scout soldiers as they dismount in close proximity to the enemy or while mounted.
The improvement will cover the flat-bottom hull and double v-hull platforms, as well as cannon application and improvement.
US Army Stryker Brigade Combat Team project manager colonel Glenn Dean said: "The next round of upgrades is intended to improve the lethality of the Stryker formation, so it's important to find solutions that work well in concert, and go beyond just making an individual vehicle more lethal.
"The team is particularly interested in enhancements that are readily available, such as commercial-off-the-shelf, as well as technologies that will be available in the near-term.
"We really want to identify technologies and potential contributors that we haven't specifically looked at yet."
According to the US Army Program Office, other solutions such as sensor, protection, or platform network upgrades would also be considered.
Dean added: "Though ultimately we're not going to be limited by technology, we'll be limited by budget.
"We will have to select the best mix of affordable capability consistent with priorities outlined in the Army's Combat Vehicle Modernization Strategy."
Last July, the army approved a directed requirement to increase lethality for 81 Stryker vehicles for the 2nd Cavalry Regiment.
As part of the requirement, an accelerated acquisition effort is currently underway to integrate a 30mm cannon on an unmanned turret, with fielding required by 2018.
