Combat salvo analysis was a field of study relating to the effective use of photon torpedoes. In the 2250s, models of salvo analysis considered by Starfleet included the traditional Neo-Wayne model and the Onafuwa model.
During this period, Una, who found the Onafuwa model to be problematic, worked on a memorandum highlighting the urgent need for quantum-stochastic combat models of salvo analysis, which required an in-depth analysis of the accuracy of Starfleet's most advanced torpedoes. The memorandum stated that gathering intelligence on both their offensive and defensive firepower was essential to Starfleet's survival. (ST: "Q&A")
