Overview

---

The Internal Structure of a BattleMech forms the skeletal structure of the 'Mech to which all components are mounted.

Standard Internal Structure

The Standard Internal Structure of a 'Mech weighs 10% of its max. tonnage (i.e. on a 100 ton Atlas the internal structure weighs 10 tons).

It is the least bulky structure and does not take up any Critical Space. It is also the least expensive and converting a 'Mech to it costs the 'Mechs maximum tonnage x 5,000 (on an Atlas, it would cost 500,000 ).

Endo-Steel Internal Structure

The Endo-Steel Internal Structure of a 'Mech weighs only 5% of its max. tonnage (i.e. on an Atlas, it would only take up 5 tons), but requires 14 Critical Spaces.

However, converting to Endo-Steel costs the 'Mechs max. tonnage x 10,000 (on an Atlas, it would cost 1,000,000 .

Savings

Compared to the weight saving of Armor, switching to an advanced internal structure provides a greater saving, i.e.:

Commando (25 t): Armor (Standard : Ferro Fibrous) 8.06 : 7.47 t vs. Structure (Standard : Endo Steel) 2.5 : 1.5 t = armor 0.59 t vs. structure 1 t

Cicada (40 t): Armor 12.56 : 11.65 t vs. structure 4 : 2 t = armor 0.91 t vs. structure 2 t

Hunchback or Centurion (50 t): Armor 35.57 : 34.44 t vs. structure 5 : 2.5 t = armor 1.13 t vs. structure 2.5 t

Cataphract (70 t): Armor 20.56 : 19.11 t vs. structure 7 : 3.5 t = armor 1.45 t vs. structure 3.5 t

Atlas (100 t): Armor 29.19 : 27.13 t vs. structure 10 : 5 t = armor 2.06 t vs. structure 5 t

Upgrading the Structure

To switch between Standard and Endo-Steel Internal Structure, use the Upgrades tab in the Mech Lab and choose structure.

• Switching to Endo-Steel requires that you have enough money and Critical Spaces available on your 'Mech.
• Switching to Standard Structure requires that you have enough money and tonnage available.
