NEWTOWN, Conn. --- The United States Navy maintains such an extensive inventory of sonobuoys that it should come as no surprise a number of them expire while sitting on the shelf. Those units with an expiring shelf-life will need to be replenished, or at the least will be in need of battery replacement.
During the past several years, the U.S. Navy has been announcing additional procurements of the SSQ-53F sonobuoy -- a move long projected by Forecast International's naval analysts - at predictable intervals. Thanks in part to contract modifications to the original contract awards, many thousands of SSQ-53F sonobuoys will be delivered by the end of 2017.
From 2018 through 2020, SSQ-53F sonobuoy replenishment will likely be minimal, given the fully stocked inventory; however, starting in 2021, another round of replenishment orders can be expected as the sonobuoys' batteries begin to expire and technological advancement are applied.
