Regardless of whether IAF wants SFDR or not, it is wise to phase out Astra MK1 with dual pulsed motor Astra MK2. So, IAF can have combination of SFDR and Astra MK2 instead of Astra MK1 and SFDR. It is impractical to have only SFDR as sole AAM due to difficulty in mass manufacturing such complex missile. So, another AAM is definitely needed. The question is about whether to mass manufacture Single dual thrust motor Astra Mk1 OR dual pulsed motor Astra Mk2 as standard AAM for IAF in addition to SFDR.
