Recently, a gauged linear sigma model was proposed by Berkovits and Vafa which can be used to describe the AdS 5 × S 5 superstring at finite and zero radius. In this paper we show that the model is classically integrable by constructing its first non-local conserved charge and a superspace Lax ''quartet''. Quantum conservation of the non-local charge follows easily from superspace rules.
