US Navy Ship Deployments: Frequency, Duration, and the Role of Ports

The frequency and duration of US Navy ship deployments depend largely on the mission and circumstances. This article explores the dynamics of these deployments, the role of port visits, and the challenges faced by sailors during extended periods at sea.

Frequency and Duration of Deployments

The exact duration of a US Navy ship deployment can vary widely. For instance, during my first deployment on the USS Spruance Class Destroyer DD-971, we engaged in a Show the Flag mission. This meant that we port hopped, staying in port for a few days before sailing to the next destination. This pattern continued for six months. In contrast, one of my deployments lasted for eight months, during which we visited three ports for a total of 16 days.

Typically, an average mission lasts around 90 days, though it can extend to several months. For example, the USS Stout DDG-104 spent 215 days at sea during the COVID-19 pandemic. However, it is rare for a large surface ship to remain at sea indefinitely due to maintenance requirements and supply replenishment needs.

Role of Ports During Deployments

During deployments, ships frequently return to port for resupply and maintenance. In port, they can restock food, replace supplies, and even conduct rest and recovery periods for crew members. One notable instance involved the USS America CV66 during the Iranian hostage crisis, where the ship was at sea for nearly 68 days without visiting any foreign ports.

In contrast, during a deployment to the Mediterranean (e.g., on the USS Sylvania AFS2), the ship visited ports regularly to resupply and distribute resources to the Sixth Fleet. Additionally, USS New Orleans LPH-11 was off the coast of NAM for 58 days, and two weeks was not an uncommon duration for port visits. In some cases, sailors may feel confined or less engaged when at sea for extended periods during training exercises, such as those in the Philippines jungle.

Challenges of Extended Deployments

While deployments provide opportunities for ships to participate in various missions such as Show the Flag or training exercises, they also present significant challenges. For submarines in particular, leaving base is much less frequent than for surface ships due to their covert nature. Surface ships, on the other hand, can remain in sea for extended periods, but they must eventually return to port to ensure the readiness and welfare of the crew.

During peace time, the primary reason for staying at sea indefinitely is very rare. While theoretically, a ship could stay at sea until it breaks down, this is extremely unlikely in the absence of emergencies. In cases of prolonged deployments, ships rely on replenishment at sea (RAS) by tankers, supply ships, and aircraft to maintain operational readiness.

In conclusion, the frequency and duration of US Navy ship deployments vary greatly depending on the nature of the mission. Port visits are crucial for resupply and maintenance, while extended deployments present unique challenges for both the ship and its crew.
