The Oklahoma City Fire Department placed an order for three custom tankers and two CR100 aerial ladders, making OCFD one of the largest E-ONE fleets in the country and the largest active E-ONE aerial fleet with 18 aerials in service.

The three tankers have a 3,000-gallon water capacity, an increase from their previous 2,500-gallon tanker design.

The aerials offer a heavier tip load and lighter-weight aluminum construction.
