In 1994 and 1990 Kristensen also co-authored the following two Neptune Papers monographs published by Greenpeace International:

• Aircraft Carriers: The Limits of Nuclear Power, Neptune Papers No. 7, Greenpeace, Washington, D.C., June 1994 (pdf 1.9 MB).
  The report analyzes the performance of nuclear-powered versus cheaper oil-powered aircraft carriers and compare actual performance with the U.S. Navy’s claims of unique benefits from nuclear propulsion. A review in the U.S. Naval Institute Proceedings called the study “invaluable” to the assessment of the U.S. Navy’s carrier building program and stressed that the report “should be read by everyone in the administration, Department of Defense, and Congress who will participate in decisions related to future carrier programs.” The report’s conclusions were reaffirmed by the U.S. General Accounting Office’s report Navy Aircraft Carriers: Cost-Effectiveness of Conventionally and Nuclear-Powered Carriers from 1998.

• U.S. Naval Nuclear Weapons in Sweden, Neptune Papers No. 6, Greenpeace, Washington, D.C., October 1990 (pdf 3.4 MB).
  The report investigates Swedish non-nuclear policy and the nuclear history of U.S. Navy ship visits to Swedish (and other Scandinavian) ports during the Cold War. The report documents how U.S. warships as a matter of routine brought nuclear weapons into Swedish ports despite the country’s ban against such weapons. The U.S. government turned down a request from the Swedish government to comment on the findings and the Swedish ruling party subsequently decided to enforce its non-nuclear policy during port visits, similar to that of New Zealand. Before the decision was carried out, the U.S. government suddenly announced in September 1991 that all tactical nuclear weapons would be removed from ships and submarines.

Other publications worth listing that I contributed to:

• William M. Arkin and Joshua Handler, Naval Accidents 1945-1988, Neptune Papers No. 3, Greenpeace/Institute for Policy Studies, June 1989 (0.6 MB).
  The report documents 1, 276 accidents of the major navies of the world with a focus on those that involved nuclear-armed or nuclear-propelled vessels. This includes ten accidents where nuclear weapons and/or nuclear reactors were lost at sea, as well as hundreds more where nuclear-armed vessels were involved in accidents.
