The FTCA is the «exclusive means by which a party may sue the United States for money
damages... in tort»
pursuant to 28 USC § 2679, but this is really something of an exaggeration as there are lots of constitutional and
statutory grounds upon which the United States government can also be sued for money
damages that naively appear tort - like, such as a reverse condemnation action under the 5th Amendment to the United States Constitution.
