A brand new contract choice is transferring the US army’s world-class Abrams tank in a course it is by no means gone earlier than: after a long time of getting bulkier amid upgrades so as to add firepower and cutting-edge safety, it is lastly getting a critically wanted slim-down.
Protection Information was first to report on the finish of Could that the Military had awarded a contract to Abrams producer Basic Dynamics Land Programs (GDLS) to start out creating necessities for what it is calling the M1E3 — a brand new era of Abrams tank.
Reached for particulars on the contract, GDLS referred all inquiries to the Military’s PEO Floor Fight Programs, which didn’t reply to Sandboxx Information’ queries. Whereas the Protection Division printed award notices for a number of smaller Abrams contract modifications in Could, it seems the main points of this design contract haven’t but been made public.
This begins a brand new period of improvement for the Abrams, and the primary of its variety in a long time: the final full M1A2 rolled off manufacturing traces in 1996. But, the duty of rolling out a modernized tank — one that should lower greater than 10 tons from its preventing weight — is formidable.
The M1A2 Abrams is in a weight class of its personal among the many world’s main tanks: the present variant, the SEPv3, weighs round 70 tons by itself, and as much as 78 with a full fight load. As a comparability level, 78 tons can be the utmost takeoff weight for the Airbus A320, a passenger plane with a capability for 180 souls.

The heft of the Abrams tank has enabled its dominance as one of the vital formidable foremost battle tanks in service; however as its weight has grown with every replace, it has additionally began to restrict its mobility.
In 2017, a three-star Military common revealed to Congress that the tank might now not be towed by the Heavy Tools Transport car particularly designed to tow it — that means there was nothing that might haul the Abrams round Europe, the place a quantity had been positioned as a part of an initiative to discourage Russia.
Bridges are additionally an issue, significantly in Europe the place many crossings are outdated and never bolstered; there, a single Abrams represents a significant structural menace. With a present scorching battle in Europe, these drawbacks have been more and more regarding to planners. In September, the Military introduced it was canceling a deliberate improve — the M1A2 Sepv4 — that threatened to fatten the Abrams much more, and as a substitute pursue a extra radical modernization.
“The Abrams tank can now not develop its capabilities with out including weight and we have to cut back its logistical footprint,” Maj. Gen. Glenn Dean, program government officer for the Military’s Floor Fight Programs, stated in an announcement accompanying the announcement. “The struggle in Ukraine has highlighted a vital want for built-in protections for troopers, constructed from inside as a substitute of including on.”

To this finish, the Military is asking for $246 million for the following fiscal yr, with plans to spend one other $366 million on tank upgrades in fiscal 2026. A paper developed by the Congressional Analysis Service lays out the Military’s major aims for modernization. It cites a 2019 Military Science Board examine that reportedly influenced the trail the service is at present on.
A few of them would merely undertake applied sciences already in use by different premier tanks, resembling an autoloader, which could permit the Abrams to make use of a crew of three as a substitute of 4 and lower down on manpower. The French Leclerc and South Korean K2 Black Panther have already got autoloaders, as do Russian, Japanese, and Chinese language tanks. Additionally proposed is a brand new foremost gun in lieu of the Abrams’ legacy 120mm L/44 M256 smoothbore armament.
Different proposed options would improve the Abrams’ stealth; these embody “masking” tech that reduces thermal and electromagnetic signatures and a hybrid-electric drive, a characteristic that usually allows silent standby mode.
Basic Dynamics’ AbramsX demonstrator, integrated many of those options. It constructed within the autoloader and the hybrid drive and swapped in an XM360 tube on the primary gun to chop the weapon’s weight in half.
Along with different wish-list options, like higher command-and-control capabilities and the flexibility to launch drones and community with unmanned and robotic methods, the AbramsX purportedly achieves the all-important slimdown the Military desires, weighing in at a relatively svelte 60 tons. It achieves a lot of those financial savings by relocating the crew contained in the hull, permitting for a significant armor discount on the turret.
And herein lies the largest problem for the Military in its quest for a lighter tank: the bulkiest options the Abrams sports activities are the armor and protecting methods that make it so formidable. The Abrams Reactive Armor Tiles that cowl the tank’s floor alone add two extra tons of weight — however the tiles successfully blast incoming rockets away from the car’s floor, including a next-level layer of safety.
The Abrams’ Trophy Lively Safety System, an Israeli-developed countermeasure that detects and intercepts incoming threats very like a miniature Iron Dome, provides practically 4 extra tons. That actuality has spurred hypothesis as as to whether Trophy can be featured on future generations of the Abrams.
The fact is that the M1 Abrams has gotten so heavy by means of its cycle of including new protections onto its rugged body as they turn into state-of-the-art: due to this fact, it’s a cross-section of lots of the finest methods the world’s tanks have to supply. To chop weight, the Military should undertake an aggressive redesign to make a few of these methods inner to the car; however it might additionally need to make some robust tradeoff choices about what the next-generation Abrams actually wants to satisfy tomorrow’s threats.
It’s left to be seen which options belong in Abrams’ future, and which can be left prior to now.
