This paper describes MUSTANG 2, a 338 element focal plane array that is being built for the Green Bank Telescope. Each element consists of a profiled feedhorn coupled to two transition edge sensor bolometers, one for each polarization. Initial deployment will be with 32 detectors, but once fully populated, MUSTANG 2 will be capable of mapping a 8′ × 8′ area to 23 μ Jy in 1 h with good image fidelity on angular scales from 9" to 6′. As well as an instrument overview, the choice of bandpass and the design of the feeds, detectors and readout are given.
