Thus outfitted, she lost excess topside weight and had better fields of fire for her anti-aircraft battery.

The hanger, flight deck and island represented a significant increase in the ship's topside weight.

These features would have been crucial to a ship that had so much topside weight added after its original design.

As she fought to survive, jettisoning topside weight, her gunners helped to destroy five enemy planes.

The modifications improved the ship's stability by helping compensate for the increased topside weight of the double hangar deck.

If the temperature is low enough this water can also freeze on the deck, rails, turrets, and other exposed surfaces, increasing the topside weight.

This jacket weighs 12,400 tonnes and supports a topside weight of around 22,560 tonnes.

This jacket weighs 3,414 tonnes and support a topside weight of around 8,000 tonnes.

During a yard availability at Mare Island, the destroyer's topside weight was cut down as 20-millimeter antiaircraft guns replaced two banks of her torpedo tubes.

This large antenna and yoke had to be strong enough for sea service, while remaining as light as possible to avoid excessive topside weight.
