Egyptian President Abdel-Fattah El-Sisi attended a display by the Egyptian naval and air forces on Thursday as part of celebrations marking the 50th annual Egyptian Naval Day, El-Sisi's office said in a statement.
El-Sisi watched the manoeuvres from aboard a Mistral helicopter carrier, off the coast of Alexandria.
During the display, the forces performed a number of feats, including securing different targets and forming a guard force.
Two Type-209/1400 modern submarines also took part in the show.
Earlier on Thursday, El-Sisi hoisted the Egyptian flag on four new additions to its naval forces: a Gowind 2500 corvette, two German Type-209/1400 submarines, and the mistral helicopter carrier.
El-Sisi also inspected recent improvements at a naval base in Alexandria, which included new quays and a new airstrip.
