Teóricamente el C295 es AEW&C, monta dos radares EL/2075 AESA más un EL/2032 que es el que trabaja blanco terrestre/naval y es el que da GMIT over SAR, con 6 consolas únicamente. El 2075 te da 360 grados en TWS (Track While Scan) otra cosa es que haga SPOT, cosa que también hace el 2032, y es que determinando el sector, que pueden ser 180 o 120 grados, juegas aumentando la potencia y con ello el alcance en ese lóbulo, bien para mapear, vigilar o lo que quieras hacer en él, eso hace que el resto de los sectores sufran una cierta "degradación" por potencia emitida, con lo que reduces alcances de detección.
Incluso puedes bloquear el sector y darle el 100% al sector, como si fuera un SLAR.
Una de las grandes dudas del C-295 s como se comportaría la plataforma con los dos radares funcionando, porque necesitas mucha generación eléctrica para ello.
E-7 monta un MESA de 3 caras, con 10 consolas a bordo, 5 contra 5 a espaldas unos de otros, es otra concepción de plataforma destinada a ser el verdadero sustituto del E-3, la altura de operación típica del C295 está entre Fl 220/240, donde fácilmente te puede dar 300km con soltura, un E-3 opera entre 250/270 con los modos Pulse Doppler Non-Elevation Scan (PDNES); Pulse Doppler Elevation Scan (PDES); Beyond-The-Horizon (BTH); Pasivo; Marítimo o Standby, en PDES sigue sin problema 600 objetivos a 250nm, imaginaos lo que hace un E-7 se va a 390/410nm sin ningún problema.

Theoretically the C295 is AEW&C, it mounts two EL/2075 AESA radars plus an EL/2032 which is the one that works terrestrial/naval target and is the one that gives GMIT over SAR, with only 6 consoles. The 2075 gives you 360 degrees in TWS (Track While Scan), another thing is that it does SPOT, which the 2032 also does, and by determining the sector, which can be 180 or 120 degrees, you can increase the power and thus the range in that lobe, either for mapping, surveillance or whatever you want to do in it, which means that the rest of the sectors suffer a certain "degradation" due to the power emitted, which reduces detection ranges.
You can even block the sector and give 100% to the sector, as if it were a SLAR.
One of the big questions about the C-295 is how the platform would behave with both radars working, because you need a lot of power generation for this.
E-7 mounts a 3-sided MESA, with 10 consoles on board, 5 against 5 with their backs to each other, it is another platform conception destined to be the real replacement for the E-3, the typical operating altitude of the C295 is between Fl 220/240, where it can easily give you 300km with ease, an E-3 operates between 250/270 with Pulse Doppler Non-Elevation Scan (PDNES) modes; Pulse Doppler Elevation Scan (PDES); Beyond-The-Horizon (BTH); Passive; Maritime or Standby, in PDES it tracks 600 targets at 250nm with no problem, imagine what an E-7 does at 390/410nm with no problem
The Active Electronic Steering Array (AESA) radar is installed in a fast rotating dome located high above the fuselage providing full 360º coverage. During the radar antenna’s rotation, the radar beams can be electronically steered in azimuth and elevation. For special high priority target surveillance the Radar can remain stationary and provide highly accurate tracking of targets within a 120º sector. The 4th generation AESA radar provides adaptive scan and track regimes, accurate 3 dimensional tracks, height measurements, electronic beam stabilization during banking, low false alarm rates and high revisit time.
