This is I believe the M60-2000
In the late 1980s GDLS developed an upgrade package for the M-60, both for export and US M-60A1 and A3 tanks (at the time, whether or not the Army National Guard and US Marines would receive their M-1 Abrams tanks in a timely fashion was in doubt). This upgrade package included improvements to the armor, power pack, fire control system, and ammunition storage. Though as of yet this upgrade package has not been picked up by any M-60 users, most of which are buying newer-design tanks. Upgrades include fire control upgrades include a modified version of the M-1 Abrams gun stabilization system, ballistic computer upgrades, and upgrades to existing systems controlled by the ballistic computer. The engine is replaced by one of two versions of the AVDS-1790, developing 908, 1050, or 1200 horsepower; the transmission is also upgraded to match the new engine. The suspension is also upgraded, giving a smoother ride and better fire-on-the-move. New tracks are fitted. Armor protection is greatly improved using appliqu armor, and ERA lugs are standard. The turret has an enlarged bustle with blow-out panels similar to those on the M-1 Abrams, and offering the same protection in the case of a turret ammo explosion. Improved and rearranged ammunition storage allows for more ammunition to be carried. The cupola is replaced with a conventional commanders station, with vision blocks and an M-2HB heavy machinegun that can be aimed and fired remotely. Israel devised an ERA kit for the M-60A3, and this was quickly picked up on for US Marine M-60A3s and some US Army M-60A3s that were still on active duty. Often these vehicles also have track skirts added. Many other countries operating the M-60A3 and M-60A1 also applied ERA to their M-60s. (The M-60A3 with ERA is the tank that the US Army Vehicle Guide and American Combat Vehicle Handbook refer to as the oeM-60A4.). The faces covered by a full kit include the HF, HS, TF, TS, and the forward part of the turret deck. There is a kit to extend the mount for the smoke grenade launchers that may be fitted when the TS ERA is applied.
This is the M60-M120S.
At first referred to by as the M-60-2000, GDLS now refers to this Abrams/M-60hybrid as the M-120S, with the oe120 referring to the gun caliber and oeS referring to Survivability. The M-120S is an attempt by GDLS to quickly and less expensively produce a dramatic upgrade for the M-60 series. The M-120S (an unofficial, company designation), is still being marketed heavily by GDLS, and came within a hairs-breadth of being adopted by Turkey (already the user of a large fleet of M-60A3s), but as yet no sales have been made. Egypt has also shown some interest in the M-120S, as they too have a fleet of former-US M-60s. Though the M-60 chassis is obvious with a close look, the M-120S does have a great resemblance to an actual M-1A1 Abrams. The turret is essentially the same as that of the M-1A1, but with no DU armor inserts. The turret is mounted on the M-60 chassis with an adapter ring. As the M-1A1 turret is much heavier and extra armor is added to the M-120S, the suspension has been beefed up considerably to take the extra weight, and the tracks have been replaced with lighter, yet stronger ones. The standard torsion bars have been replaced with hydropneunmatic units to smooth the ride, as well as saving space within the hull. The sponsons have been enlarged to hold batteries and extra fuel. The powerpack has been replaced with an AVDS-1790-9 1200 hp diesel and a matching automatic transmission. The M-120S uses M-1A1-type final drives and M-1A1-type drivers controls. Armor enhancements include side skirts and Chobham glacis armor, as well as general hull armor augmentation and lugs for ERA on the HS and TS. The M-120S has an external APU similar to that used on some versions of the Abrams, a digital command-and-control computer, thermal vision for the driver, a CITS (Commanders Independent Thermal Sight), general improvements to the electrical system, and monitors for the vehicle equipment condition.
