Augmenting its current lineup of Electron rocket systems, Rocket Lab hopes that Neutron will be the rocket of choice for companies wanting to build their own satellite constellation networks. Rocket Lab has been very successful with its Electron rocket, but it also wants to offer a more capable service. Rocket Lab recently debuted its new Neutron launch pad ahead of planned engine tests (and eventually full flight).
