S-300V4 / S-350 Vityaz / Pantsir-S1/SM

S-300V4 is a long-range theater-defense variant of the S-300 family, optimized for ballistic threats (range up to 400 km with 9M82 missiles, ceiling 30 km); the main user outside Russia is Egypt. S-350 Vityaz is a more recent medium-range system (50–60 km) with active phased-array radars that replaces the S-300PT/PS in local Russian air defense. Pantsir-S1/S2/SM is a unique gun-plus-missile combination on a single 8×8 truck: two 30 mm 2A38M cannons for short range (1–4 km) plus 12 57E6 missiles in canisters for medium range (1.2–20 km). Pantsir uses command-link guidance (no autonomous seeker), making it vulnerable to saturation attacks and EW. RUSI analyses (2023) noted that Pantsir is mainly effective inside a layered SAM network; standing alone it is regularly knocked out by Bayraktar TB2s and HIMARS rockets (Oryx open-source count: ≥20 lost in Ukraine).
