War Thunder Update v2.49.0.73 Fixes Top-Tier Composite Armor Calculations

War Thunder update v2.49.0.73 fixes a critical composite armor calculation bug affecting the turret roofs of Merkava Mk.4 and Strv 122 tanks. The patch also addresses interface and replay errors.

War Thunder update v2.49.0.73 corrects an armor calculation error that made certain high-tier main battle tanks unusually resilient against top-down ordnance. The minor patch also resolves interface visibility bugs and replay camera detachment.

Merkava and Strv 122 Armor Fix

A calculation error for all variants of the Merkava Mk.4 and Strv 122 is corrected. Previously, composite armor on the turret roof was incorrectly treated as a solid sheet of steel against high-explosive shells, causing overestimated protection at certain angles that allowed these vehicles to survive direct hits from heavy air-fired missiles and large-caliber bombs.

Interface and Replay Corrections

The update resolves an interface bug that prevented the nuclear-equipped aircraft spawn option from appearing for Multi-Vehicle SAM system launchers. It also fixes an incorrect laser warning direction indicator when vehicle hulls were misaligned with the threat, prevents aircraft radar indicators from freezing when switching targets, and stops replay free cameras from detaching after respawns.

Why this patch matters

Update v2.49.0.73 delivers a precise, high-priority fix for top-tier ground vehicle survivability, restoring proper vulnerability to roof-striking ordnance.
