The Periphas is a delta-wing, twin-tailed, air superiority/strike fighter produced by Syara. The Periphas was the first Syaran fighter to incorporate fifth generation characteristics such as stealth technology, super-maneuverability, and advanced avionics.

The concept for the Periphas first surfaced during the 1990s as the Commonality Air Force expressed a desire for a high-end, advanced fighter aircraft superior to other air superiority fighters. The demand for such an advanced fighter resulted in a protracted development that eventually culminated in the Periphas. The first flight was conducted in 2001 and the aircraft entered into service in 2007, following an accelerated development path as a result of the Imerti Conflict. The rushed design left the Perihpas a flawed machine, and adjustments were still being made to the design by the time of the Zemplen War.

Although the Periphas was a capable machine, the aircraft earned a poor reputation among many Syarans. It was dubbed "кралица на хангар" or "hangar queen" because of its extensive maintenance requirements; the radar absorbent material had to be re-applied after most sorties, the aircraft's radar system was prone to malfunction, and some pilots claimed the aircraft was unstable at angles of attack beyond 50 degrees, although others reported no issues. The excessive cost of maintaining the aircraft (on top of its already high cost per unit) meant it saw only limited service during the war.

Following the conflict the Periphas received several upgrades meant to improve the performance and maintenance of the aircraft. These continued until 2017, when it was announced that the Aeolus, which had been influenced by the Periphas, would be adopted by the CAF. The remaining Periphas' in service are expected to serve until the 2040s.
