This name generator gives you 15 random names for all kinds of siege-engines from defensive to offensive, some names are better for certain types of siege-engines. 'The Tortoise,' for example, appears to match better defensive siege engines. However, with some creativity, most of the names could match any form of siege engine in some way depending on the culture and technology behind it. The names were loosely based on existing (nick)names of siege engines, but we added a lot more styles and forms that were not already used. There's a lot to choose from.
