Ok..
Waynos et all..
a quick course in al EW 'protrusions' on this a/c!
The RWR on the tail as well as the rear tip of the fuselage?

The 'raised' fuselage backbone EW has a weird protrusion at the front base of the vertical tail.
Actually another off-topic aerodynamics question:
The absence of the horizontal tail fins on the Tejas compromise manueverability?
And thus gains in what department?
This from wikipedia:
The tailless, compound-delta planform helps keep the Tejas small and lightweight — in fact, it is reputed to be the smallest and lightest
4th-generation combat jet in the world.[33] The use of this planform also minimises the control surfaces needed (no tailplanes or foreplanes, just a
single vertical tailfin), permits carriage of a wider range of external stores, and confers better close-combat, high-speed, and high-alpha
performance characteristics than comparable cruciform-wing designs.
Extensive wind tunnel testing on scale models and complex computational fluid dynamics analyses have optimised the aerodynamic configuration of the
LCA, giving it minimum supersonic drag, a low wing-loading, and high rates of roll and pitch.
how does the lack of hort tail fins confer better alpha and close combat performance?
