What did the A129 Mangusta's armor protect?

Short answer

The fuselage: the A129's airframe is armored and, according to All-Aero, designed to protect against 12.7 mm rounds (pending confirmation), with partial protection against 23 mm rounds. On the rotors the figures differ according to different sources: its composite blades would either withstand 23 mm cannon fire or tolerate 12.7 mm bullets (according to different sources).

An angular, armored fuselage

The A129's fuselage is highly angular and armored to provide ballistic protection. All-Aero states that the structure, built 70% from composite materials, is designed to protect against 12.7 mm rounds (pending confirmation), offers partial protection against 23 mm rounds, and meets crash-impact resistance standards.

Rotors: 23 mm or 12.7 mm

On the rotors the figures don't match, according to different sources. One version holds that the composite rotor blades also withstand 23 mm cannon impacts. All-Aero, on the other hand, states that the main and tail rotors are designed for a 12.7 mm ballistic tolerance (according to different sources). No manufacturer documentation has been found to clarify which of the two figures is correct.

Tandem crew and A109 heritage

The two crew members sit in tandem under a low-glint canopy with a small frontal area, intended to reduce visual and radar detection. Agusta first studied a combat derivative of its A109 helicopter but decided to undertake a more ambitious design. Even so, the A129 shares quite a few design features with the A109, from which its rear section is derived, joined to an entirely new front section.
