Whhile e.g. AH-64D Apache has a AN/APG-78 Longbow fire control radar, that radar and its weapons counterpart, the radar-guided, "fire and forget" Longbow Hellfire missile, enable the potent Apache attack helicopter to detect, classify and prioritize ground targets day or night, in poor weather and obscured conditions; then attack those targets with pinpoint accuracy from ranges that safeguard the lives of the aircrew. Likewise Mi-28N/MMW Havoc with Ataka missiles
