 However, progress in the "Kaveri" development programme was slowed by both political and technical difficulties.In 2002, little information had been publicly released concerning the nature of the "Kaveri" technical challenges, but it was known that the "Kaveri" had a tendency to "throw" turbine blades, which required securing blades from SNECMA (as well as digital engine control systems).Continuing development snags with the "Kaveri" resulted in the 2003 decision to procure the uprated F404-GE-IN20 engine for the eight pre-production Limited Series Production (LSP) aircraft and two naval prototypes.
