Five companies you didn’t know were in the arms industry

While companies such as Mitsubishi and Rolls Royce are well-known for producing everything from motorbikes to air conditioners, they're not the only products the companies are manufacturing.

The Stockholm International Peace Research Institute's (SIPRI) most recent edition of its Arms Industry Database, includes a ranking of the top 100 companies involved in arms-production.

The ranking shows that 42 of the top 100 companies are US-based — while this isn't particularly shocking, it may come as a surprise that a number of the companies involved in arms-dealing are much better known for manufacturing other products, such as vehicles and household appliances.

Here are 5 of the biggest tech companies you may not have known also manufacture arms.
