Evidence & current status
The sources below establish the stated programme milestone or supplier claim. They do not independently verify every configuration, delivery total or advertised performance figure.
Role and programme
The LASSO announcement establishes a funded development, delivery and testing activity. A prototype agreement should not be described as full-rate production, operational acceptance or a completed delivery programme.
The manufacturer presents Switchblade 400 as a portable medium-range loitering munition. It is a distinct product from the 300 and 600 families, so neither neighbouring model supplies its missing numerical specifications. The cited announcement supports the programme’s identity and maturity but leaves most airframe and flight-performance fields unresolved.
Sourced specifications
Figures apply to the named configuration. Maximum values are not guaranteed operating performance.
