Starbase Expanse 4

Starbase Expanse 4 is a Federation deep space station and planet-based starbase near the Typhon Expanse. In 2372, both the orbital platform and planetary base of SE4 was destroyed by a Myhr'an orbital attack. The USS Marsh and USS Ruapehu were also both destroyed. There were survivors who were not in the area during the attack, including Dakota Caldwell and Yh'ahni. Others, such as Lieutenant Commander D'Angelo, Lieutenant Marie Senegal and Counselor Leslie Hernandez, the three of whom were slated to join the Cantabrian team, were killed in the attack.
