t23

T23 is a designation that has been used for several different projects and items, most often in military nomenclature. The best-known reference is to a family of United States armored vehicle prototypes from World War II designed to provide a successor path to the M4 Sherman.

United States armored vehicle program: The T23 designation referred to a series of medium tank prototypes developed in the early 1940s. Variants such as T23 and later T23E1, T23E2, and T23E3 were built to test improvements to hull design, suspension, turret arrangement, and armament. The goal of these programs was to increase armor protection, mobility, and firepower compared with contemporary Sherman designs. Although the T23 prototypes demonstrated useful concepts, none of the models entered mass production. The testing and design work contributed to postwar tank development, most notably influencing the later M26 Pershing, which incorporated a heavier chassis and a more capable main gun.

Other uses: The designation T23 has also appeared in unrelated contexts, including non-armor equipment, vehicles, or product codes in various countries and industries. Because the same label can apply across different fields, precise identification typically requires specification of the domain (military, transportation, consumer products, etc.) and the country of origin.

In summary, T23 most prominently refers to WWII-era American tank prototypes that informed later armored vehicle development, while in other contexts the label can denote a range of unrelated items. If you have a particular domain in mind, I can provide a more targeted overview.
