MEMORANDUM **

Ronald Nardizzi, a former employee of a non-appropriated fund instrumentality (“NAFI”) 1 on a United States Naval Base, appeals from the district court’s dismissal of his claims for violations of his Fifth Amendment due process rights and intentional interference with contractual relations, as well as its denial of his motion for leave to amend his complaint. The district court dismissed Nardizzi’s Fifth Amendment claim for lack of subject-matter jurisdiction, holding that Congress intended to preclude NAFI employees from bringing constitutional claims for damages against a supervisor. The district court also dismissed Nardizzi’s claim for intentional interference with contractual relations because the United States has not waived its sovereign immunity with respect to tort claims for interference with contract.

We have jurisdiction over this appeal under 28 U.S.C. § 1291 and review de novo a district court’s dismissal of a complaint under Federal Rules of Civil Procedure 12(b)(1) and 12(b)(6). Viewtech, Inc. v. United States, 653 F.3d 1102, 1103-04 (9th Cir. 2011); Harkonen v. U.S. Dep’t of Justice, 800 F.3d 1143, 1148 (9th Cir. 2015). We affirm the judgment of the district court.

In certain circumstances, a plaintiff may bring an action for constitutional violations by a federal officer under Bivens v. Six Unknown Named Agents of Fed. Bureau of Narcotics, 403 U.S. 388, 397, 91 S.Ct. 1999, 29 L.Ed.2d 619 (1971). Such an action is unavailable, however, when “the design of a Government program suggests that Congress has provided what it considers adequate remedial mechanisms for constitutional violations,” or where there are “indications that congressional inaction has not been inadvertent.” Schweiker v. Chilicky, 487 U.S. 412, 423, 108 S.Ct. 2460, 101 L.Ed.2d 370 (1988).

In Blankenship v. McDonald, we held that a federal court reporter, who lacked access to the administrative remedies pro *800 vided under the Civil Service Reform Act (“CSRA”), was precluded from bringing a Bivens action. 176 F.3d 1192, 1195 (9th Cir. 1999). Blankenship compels the dismissal of Nardizzi’s Bivens action. There, we found that Congress’s decision to deny certain remedies to judicial employees and grant them others indicated that the lack of more complete remedies to the plaintiff was not inadvertent. Id. Similarly, NAFI employees have access to certain administrative remedies to challenge a termination through the Navy Personnel Manual, and Congress explicitly excluded NAFI employees from the remedial scheme of the CSRA, see 5 U.S.C. § 2105(c). Therefore, Congress’s decision to deny a more complete remedy to these employees was not inadvertent.

The district court also correctly dismissed Nardizzi’s tort claim for intentional interference with contractual relations for lack of subject-matter jurisdiction because Nardizzi did not challenge the district court’s substitution of the United States as a defendant in this action, and the United States is immune from suit for interference-with-contract claims under the Federal Tort Claims Act. See 28 U.S.C. § 2680(h).

Finally, the district court properly denied Nardizzi leave to amend' his Fifth ' Amendment claim to include a request for equitable relief. An amendment would be futile because the available procedures were constitutionally adequate. See Saul v. United States, 928 F.2d 829, 843 (9th Cir. 1991).

AFFIRMED.
