Vertega V-13

The Vertega V-13 Firestorm ( Vertega V-13 Tűzvihart) is a joint VSO and Granzerian supersonic, stealth multirole fighter developed by the Vertega Corporation as a low-cost alternative to the V-12 Tempest. The program is spearheaded by Granzery, holding 80% of shares, and was joined by other VSO nations in 2010 for the remaining 20% of the shares. The aircraft has similar capabilities to the larger V-12 Tempest, for approximately half the cost, the V-13 is cheaper to operate than the V-12, making it a more attractive option than the V-12 for most VSO members.

Stealth
Measures to reduce radar cross-section on the V-13 include airframe shaping such as alignment of edges, fixed-geometry serpentine inlets that prevent line-of-sight of the engine faces from any exterior view, and attention to detail such as hinges and pilot helmets that could provide a radar return. The V-13 was also designed to have decreased radio emissions, infrared signature and acoustic signature. The V-13L model in current development also makes use of fiber-mat and other stealthy, radar-absorbent materials to further increase the stealth capabilities of the aircraft while maintaining a low cost of operation.
