By the Athenian trireme era (500 BC), [1] the hull was strengthened by enclosing the bow behind the ram, forming a bulkhead compartment. Instead of using bulkheads to protect ships against rams, Greeks preferred to reinforce the hull with extra timber along the waterline, making larger ships almost resistant to ramming by smaller ones.
The hull serves as a basis for platforms on tanks, armoured personnel carriers, combat engineering vehicles, etc. In the intermodal trucking industry, a chassis is a type of semi-trailer onto which a cargo container can be mounted for road transport.
Ladder frame pickup truck chassis holds the vehicle's engine, drivetrain, suspension, and wheels The unibody - for the unitized body - is also a form of a frame. A vehicle frame, also historically known as its chassis, is the main supporting structure of a motor vehicle to which all other components are attached, comparable to the skeleton of an organism.
The strength of ships is a topic of key interest to naval architects and shipbuilders. Ships which are built too strong are heavy, slow, and cost extra money to build and operate since they weigh more, whilst ships which are built too weakly suffer from minor hull damage and in some extreme cases catastrophic failure and sinking.
To make the shell, thin strips of wood were laminated into a three dimensional shape; a technique adopted from boat hull construction. One of the earliest examples was the Deperdussin Monocoque racer in 1912, which used a laminated fuselage made up of three layers of glued poplar veneer, which provided both the external skin and the main load ...
U.S. tank crews often added sand bags in the hull and turrets on Sherman tanks, often in an elaborate cage made of girders. Some Sherman tanks were up-armoured in the field with glacis plates and other armour cut from knocked-out tanks to create Improvised Jumbos, named after the heavily armoured M4A3E2 assault tank.

The 13-sided mainframes were 49 ft (15 m) apart, and were made up of diamond-shaped trusses connected by 13 main and 12 secondary longitudinal girders and a trapezoidal keel. There were two secondary ring frames between each pair of mainframes. The forward-mounted control car was directly attached to the hull.
