Abstract: A jammer which eliminates the need for a bobtail in a forward deployment. The jammer has an outwardly extending boom with a table at the distal end of the boom. The table can mount upwardly extending cradles suitable for temporarily holding cargo, such as a munition, during transport and positioning on the underside of an aircraft wing. The table also holds an upstanding pintle hook. The pintle hook provides for attachment of the jammer to a trailer for towing. Using the jammer for both towing of a trailer and positioning of cargo using the boom eliminates the need for a bobtail, conserving both cargo space and payload weight during deployment.
