The wing-pod tanks don't weigh more than five hundred pounds, but they create an awful lot of drag at the lower altitudes and higher speeds.

The tank, which is portable enough to be placed on ships, weighs almost seven tons when filled with water.

Each tank weighed 750 pounds and could be folded up into a volume of 125 cubic feet.

But he was in space now, so the tanks weighed nothing.

The tanks held a maximum of 30 gallons, and weighed, when full 588 pounds and could lay a smoke screen about 2,000 feet long.

Seven tanks would weigh 140 tons.

In this configuration the tank weighed perhaps 74 tons.

Most amphibious light tanks weigh little and often utilize aluminum armor.

Each tank weighed sixteen point eight tonnes.

However because all tanks currently in Polish service weigh more than 40 tons it is unable to tow them.
