What are the search responsibilities for F-16s #1 and #4 during both LRS and MRS?

In the context of F-16 responsibilities during Long Range Search (LRS) and Medium Range Search (MRS), the focus is on how these aircraft prioritize their search areas to effectively track and respond to potential threats.

F-16 #1 and F-16 #4 operating under a formation or a specific tactical plan usually take on designated responsibilities. When F-16s are tasked in a search and surveillance role, the terms "Surface" and “Up” describe their respective responsibilities within the operational environment.

The term "Surface" refers to monitoring activities and threats that are on the ground or sea level, which is critical for ensuring airspace superiority as well as ground support missions. The “Up” responsibility indicates an upward search to identify aerial threats at higher altitudes, which is essential for air defense and ensuring the safety of airspace.

By assigning one aircraft to search the surface and the other to look up, this complements the group's operational tactics, allowing them to cover a wider area of responsibility without overlap, and effectively manage threats from both air and ground sources. This separation of duties enhances situational awareness and ensures that both areas are being adequately monitored for potential threats or targets.
