First, the nice thing about writing for friends of Turkmenistan is that we don't need to address any snarky comments about why a landlocked country would need a navy. Comments regarding Kyrgyz naval efforts are very much on the table.
The navy, to be ready by 2015, may signal a more aggressive defense of Caspian Sea interests. The composition of the force indicates cooperation with at least some of their neighbors (and friends of their neighbors), as ships were procured from Ukraine, Iran, Russia, and the US.
On land, Belarus and Turkmenistan have signed a separate military cooperation agreement, part of President Berdimuhamedov's visit to Belarus.
