The Modularity of the Standard Missile Family:

From the beginning, the Standard family was very modular -- it's name came from the fact that it was planned to replace the entire 3T (Talos, Tartar, Terrier) family with a single standard type of missile. Accordingly, much growth capability was built into the design itself.

The first SM-1s deployed used the same Mk 27 motor as the previous Tartar. The next Block to be deployed used the newer Mk 56 motor, which while increasing missile length by 10 inches; nearly doubled it's effective range.

The next major iteration in the Standard family, the SM-2; was essentially functionally similar to the advanced SM-1 missiles; except it finally used the space and weight which had been allocated in the design from the start for a remotely programmable autopilot, enabling inertial mid-course guidance for missiles fired from ships equipped with the proper equipment (AEGIS or NTU). This simple change allowed the SM-2 to fly a much more energy-saving flight profile, instead of having to fly an energy-wasting SARH fight profile, increasing it's range by 60% with no other changes.

The same examples also occurred in the Extended Range (ER) program. Originally, the missiles used the existing Mk 12 Terrier booster for all of the SM-1ERs and the first Block of the SM-2ER; but this was changed to the newer Mk 70 booster; which nearly doubled the range of the SM-2ER, making it possible for it to fly beyond the effective control range of existing illuminators, while at the same time improving it's capabilities against high-energy targets.
