Zusammenfassung:	The work is devoted to the development of the Focusing Aerogel RICH (FARICH). The option of the forward RICH for the SuperB project in Italy is presented. It features an aerogel-NaF radiator and MCP photodetectors. Monte Carlo simulation predicts the π / K separation at the level better than 3 σ from 0.2 to 7 GeV/ c, the μ / π separation—from 0.13 to 1.3 GeV/ c, and the kaon momentum measurement with an accuracy of about 1% at 1 GeV/ c. FARICH for the Super Charm-Tau Factory project in Novosibirsk is proposed. Monte Carlo simulation predicts μ / π separation at the level better than 3 σ for a momentum from 0.3 to 1.7 GeV/ c. A prototype will be tested on the new electron test beam facility at VEPP-4M collider.
