Biography
Rev. Carl Kabat was a Catholic priest with the Missionary Oblates of Mary Immaculate who became widely known for decades of nonviolent anti-nuclear civil disobedience. In 1980, he helped catalyze the modern Plowshares tradition when he and seven others entered a General Electric facility in King of Prussia to symbolically “disarm” nuclear weapons components, an action carried out as religious witness against nuclear war.
Kabat was arrested in that 1980 action and in later protests. In 1984, he was again arrested after breaking into a Minuteman II missile silo site near Kansas City as part of the “Silo Pruning Hooks” action; he was convicted and received an 18‑year federal sentence (serving about a decade). He continued returning to nuclear weapons sites in later years, including an arrest connected to entering the Kansas City Plant construction area in 2012. On April 1, 1994 Kabat hammered on a Minuteman III nuclear missile silo in North Dakota — a continuation of the Plowshares disarmament tradition first set by the 1980 Plowshares Eight action. He was held at the federal prison camp at FCC Florence (Teller Unit) until August 1998. The sentencing court added 18 months to his term after determining that the 1994 ND action constituted a parole violation of his prior 1984 Plowshares action sentence.
Carl Kabat was an Oblate Catholic priest who became one of the most consistently imprisoned U.S. Plowshares activists, serving an estimated 17 years in federal and state prisons across more than 30 years of symbolic disarmament actions. He was one of the Plowshares 8 — the Catholic Left activists who on September 9, 1980 entered the General Electric Re-Entry Division in King of Prussia, Pennsylvania, hammered nose cones for the Mark 12A nuclear warhead, and poured blood on weapons documents. He was convicted in February 1981 and sentenced to 5-10 years in Pennsylvania state prison. After his release he continued Plowshares actions including the 1984 Silo Pruning Hooks (Minuteman II missile silo, 18 years federal), and the 2009 Colorado missile-silo protest. He died on August 4, 2022, age 88.
Separate source-documented custody episode
The October 30 prisoner roster identifies Carl Kabat at Rockview with ElmerMaas under the Plowshares Eight heading and a three-to-ten-year sentence. The enlarged original reads Carl Kabat; Rabat in the native extraction is an OCR error, not a new alias or identity. The group context also matches the existing Plowshares Eight biography. His existing structured roster lacks a specifically identified original Plowshares Eight case. This new case documents that separate earlier imprisonment with all custody endpoints unknown. The legacy undated property-damage row with a 2007 release and later 1982/1984 cases are unchanged. October 30 is an in-prison status date, not a jail admission; no sentence-derived release or served-day total is inferred.

Contemporary anti-nuclear custody report
The prisoner update reports Carl Kabat transferred from Rockview to Huntingdon after participating in a food strike against double-celling. This is a transfer during the earlier Plowshares imprisonment, not a first admission or a release; no custody endpoint is inferred.

1995 custody evidence and limits
The Fall 1995 Pathfinder places Carl Kabat in the second year of a five-year term at North Dakota State Penitentiary for hammering a nuclear silo. The movement chronology separately documents actual April 1,1994 removal to Barnes County Jail after the North Dakota missile-field action, and a May 16,1994 five-year sentence. The five years are imposed, not completed. No release endpoint is given; do not merge this with his earlier Silo Pruning Hooks imprisonment or later parole proceedings.

February 1985 verdict and contemporary custody limits
The original trial report individually identifies Helen Woodson, Paul and Carl Kabat, and Larry Cloud-Morgan, and dates their guilty verdict on all counts to Friday, February 22, 1985. They remained in jail pending a March 25 sentencing date that was still future; it is not entered as the actual sentencing day. This account dates the N-5 action to November 12, while the previously reviewed appellate opinion’s opening narrative gives November 9 and its quoted jury instruction says on or about November 12. The conflict is preserved rather than silently moving existing arrest/admission dates. Paul’s separately documented actual March 27 sentence and official later endpoint are unchanged; this source’s forecast does not overwrite them.

1985 custody evidence and limits
The contemporary Silo Pruning Hooks report explicitly places sentencing on March 27, 1985 before Judge D. Brook Bartlett. This confirms the sentencing date for this already recorded missile-silo case; it does not settle the separately preserved November 1984 arrest/admission-day conflict, alter actual release, or convert the nominal sentence into time actually served.
The study identifies James Buckingham as the April 1990 resentencing judge and records time served plus twenty-three months’ probation.
In a June 1991 Associated Press interview, Kabat recalled five days actually served at Americus, Georgia, after an earlier anti-nuclear banner protest near Jimmy Carter’s home in Plains.
A 2022 first-person remembrance reprinted by The Nuclear Resister reports a separate overnight county-jail stay after Kabat protested an execution at the Bonne Terre prison in February 2011. The author arrived after the arrest and learned about it from guards; this is a reported custody account, not an eyewitness description of the arrest. No exact admission or release day, formal charge or numeric time-served total is inferred. Existing custody totals remain a known subtotal.
The Fall 1996 Pathfinder records transfer from North Dakota state custody directly into federal custody in early August 1996, followed by a September 23 federal parole-revocation sentence. The Fall 1998 issue explicitly reports actual release from Florence on July 10, 1998. The transfer is not entered as a release to freedom on the North Dakota row, and the earlier projected August 1998 release is superseded by the report of what actually occurred. Source.
Molly Rush’s first-person reflection dates the opening of the Plowshares Eight trial to February 23, 1981, before Judge Samuel Salus. Frida Berrigan’s separate forty-year account also identifies Salus and describes his refusal to admit the proposed expert testimony on nuclear weapons and international law. This identifies the original trial judge, distinct from Judge James Buckingham at the later April 1990 resentencing already recorded. It does not change the existing case dates, nominal individual sentence, separate jail intervals or actual-custody total.

The obituary compilation identifies his full name as Carl Kenneth Kabat. Its reproduced 2010 St. Louis Magazine account names Weld County deputy district attorney David Skarka in the Colorado missile-silo prosecution. Bill McClellan’s later remembrance describes Kabat’s separate February 2011 protest at the Missouri prison where Martin Link was being executed: Kabat was taken to the county jail and held overnight. That account gives neither an exact arrest day nor a complete measured duration.
The Nuclear Resister, August 2022 obituary and contemporary-remembrance compilation.
The Nuclear Resister’s obituary compilation explicitly corrects an earlier account to identify Kabat’s last arrest at the Kansas City nuclear weapons plant as July 4, 2019. The reproduced New York Times obituary separately reports that in 2019 he splashed red paint on an entry sign at the National Security Campus and was charged with trespassing and damaging property. This was a separate later protest from the 2016 action also described in that obituary. Neither passage establishes a jail admission, physical release date, conviction, imposed sentence or measured time in custody for the 2019 arrest.

A July 2019 report explicitly recalls Kabat’s previous arrest in July 2017 at the Kansas City nuclear-weapons components facility. Only the month is documented for that earlier arrest; this account does not establish its charge, jail admission, release, outcome or time served. Separately, the report says Kabat and Byron Clemens were detained on site for a few hours following their July 4, 2019 action; this is additional context for the already recorded 2019 case, not a second 2019 arrest or evidence of a jail term.
The Nuclear Resister, July 5, 2019, with subsequent court-report update.
The September 2012 Nuclear Resister reports that Carl Kabat entered the new Kansas City nuclear-bomb factory construction site late on July 3, slept there and was arrested after daylight. He was held in jail until the next day, arraigned on two trespass counts and one destruction-of-property count, pleaded not guilty and was released. This July 4–5 initial custody sequence is distinct from the separately reported 2011 fine and later prosecutions; no measured served-day total is asserted.
A contemporary report describes Carl Kabat’s July 4, 2017 Kansas City nuclear-weapons plant protest, where security stopped his approach and he was charged with trespassing and released. Its August 8 court appearance was prospective. This supplies context for the recorded July 2017 arrest; it does not establish a new jail term or a later court outcome.
The August 9, 2015 Nuclear Resister report describes Fr. Carl Kabat splashing red paint on a National Security Campus sign at the new Kansas City nuclear weapons plant and calling lawyer Henry Stoever as guards approached. That first account anticipated later detention and release but did not confirm the outcome. The August 11 follow-up reports that Kabat was physically released from Jackson County Detention Center the afternoon after his August 9 action. The recorded custody dates are August 9–10; the reports do not give exact hours. Neither report establishes a formal charge or subsequent court outcome. Initial contemporary report; August 11 follow-up.
Jane Stoever’s July 5, 2014 report describes Carl Kabat splashing red paint on the National Security Campus entry sign in Kansas City at 10 a.m. on July 4 and waiting there to be arrested. It expressly reports his release from a Kansas City Police Department holding cell on July 5. This is a separate 2014 event from his earlier Kansas City actions and later protests. The report does not specify a formal charge, exact holding-cell admission time, complete measured custody duration or subsequent court outcome. A September 3 court hearing was prospective. Its approximate seventeen-year lifetime imprisonment estimate is not added to his recorded custody total. Henry and Jane Stoever were warned to leave later that day, not reported arrested. The Nuclear Resister, July 5, 2014.
The July 14, 2013 Jane Stoever report individually names this person among twenty-four protesters arrested after crossing the property line at the new Kansas City nuclear-weapons-parts plant on July 13. All twenty-four were fingerprinted, photographed and detained at the Jackson County Police Department. The report gives mixed group release dates of July 13 and 14, with some releases expected July 15, but does not assign an individual endpoint to this person. No formal charge, exact jail admission, completed custody duration or later court outcome is inferred. Earlier charges against Carl Kabat for separate actions are not assigned to this event. The Nuclear Resister, July 14, 2013.
Jane Stoever’s October 13, 2012 report records Carl Kabat’s Kansas City Municipal Court disposition on October 12 before Judge Elena Franco: trespass in the July 4 nuclear-plant protest and violation of probation from the July 4, 2011 trespass. Franco accepted his stated plea of technically not guilty, found him guilty and imposed time served. The credited custody was his July 4–5 overnight stay; an earlier property charge had been dropped. The account does not document another jail admission at the October hearing or an additional completed prison term.
The contemporary account distinguishes Kabat’s entry into the Kansas City plant construction site late on July 3, 2011 from his actual arrest and removal to the downtown Kansas City jail on July 4. It explicitly reports release at 4 a.m. on July 5. He was charged with trespass; the August 16 court appearance was still prospective. The report supplies these custody dates but no exact admission time or source-measured whole-day total. Contemporary source.
Jane Stoever’s report documents Carl Kabat’s July 4, 2016 arrest after splashing red paint on doors at the Kansas City National Security Campus and release before noon that day. At his August 15 arraignment before Judge Corey Carter he pleaded not guilty. The October trial and possible six-month term were prospective, not a completed sentence.
The retrospective excerpt from Daniel Berrigan’s Swords Into Plowshares identifies Rev. Carl Kabat among the Plowshares Eight participants in the September 9, 1980 General Electric action at King of Prussia. Berrigan describes subsequent police-cell confinement and an initial charging phase alleging assault, false imprisonment, reckless endangerment, criminal mischief, terroristic threats, harassment, criminal coercion and unlawful restraint. Those initial allegations are not presented as the final convictions, and the excerpt supplies no complete individual admission-to-release interval.

The North Dakota imprisonment
A 2010 profile says Carl Kabat served “two and a half” years after receiving a five-year sentence for the 1994 North Dakota silo action. That retrospective description is retained as an approximation. The subsequent federal parole-revocation imprisonment was a separate phase following his transfer from state custody; it is not counted again as part of an additional rounded total.
