Today we would like to talk about the new reworked physics of missiles guided by the three-point method guidance, that is, guided using line of sight, which we have prepared for the La Royale major update. The current physics of line-of-sight missiles affects the missile's skyplane acceleration directly, bypassing the simulation of controls.

The new physical model for line-of-sight guidance missiles is similar to the physical model of homing missiles and operates on the missile's control surfaces. The updated physics model of missiles requires much more accurate autopilot tuning compared to the old physics model, and even compared to homing missiles. Generally, the autopilot of each such missile is a compromise between the dynamic error of the real missile trajectory from the kinematic trajectory and self-oscillations of the missile around the kinematic trajectory with a sharp change in the direction of the line of sight.

This must be taken into account by the player when launching from a high-speed carrier: it is worth trying to reduce the angular velocity of the line of sight to reduce the dynamic error.

So, for some missiles, engine control was implemented that allows significantly better control over a missile at low speed compared to aerodynamic controls (flaps, rudders, etc). We have implemented this feature on the following missiles: [h3]ATGM[/h3] [list] [*] SS.11 [*] 9М14М-2 [*] MILAN [*] MILAN-2 [*] HOT [*] HOT-2 [*] HOT-3 [*] 302 ATGM [*] HJ-8A [*] HJ-8C [*] HJ-8E [*] HJ-8H [/list] [h3]SAM[/h3] [list] [*] Roland-1 [*] Roland-2 [*] Roland-3 [/list] We have implemented a new physical model for the majority of the line-of-sight guided anti-tank and surface-to-air missiles. Here is the list: [h3]ATGM[/h3] [list] [*] SS.11 [*] 9М14М-2 [*] MILAN [*] MILAN-2 [*] HOT [*] HOT-2 [*] HOT-3 [*] 302 ATGM [*] HJ-8A [*] HJ-8C [*] HJ-8E [*] HJ-9 [*] TOW [*] I-TOW [*] TOW-2 [*] TOW-2A [*] 9М17P [*] 9М17М [*] 9М133 [*] 9М133М-2 [*] 9М133FM3 [*] 9М112 [*] 9М113 [*] 9М117 [*] 9М119 [*] 9М114 [*] 9М120 [*] 9М120F1 [*] 9М220O [*] 9М123 (helicopter) [*] 9М127 [*] 3М7 [*] GP105 [*] HJ-73E [*] GP125 [*] MGM-51B [*] MGM-51C [*] MP ACRA [*] Type-79 [*] ACRA [*] ZT3A1 [*] ZT3A2 [*] Rb53 [/list] [h3]SAM[/h3] [list] [*] MIM-146 [*] Roland-1 [*] Roland-2 [*] Roland-3 [*] RB-70 [*] RB 70 Mk.2 [*] BOLIDE [*] 9М331 [*] 9М311 [*] 95Ya6 [*] VT-1 [/list] The listed missiles will be transferred to the new physics with the release of the La Royale major update. Old physics remains for the 1st generation ATGMs with wire guidance, as well as for some 2nd generation missiles.
