In brief: The Navy had 12 courts-martial that ended in a murder conviction under Article 118, with trial dates from 2016 to 2025. The median adjudged confinement was 95.9 months (8 years). In federal court, the median prison term for 3,243 people sentenced for murder in fiscal years 2016 to 2025 was 292 months (24.3 years). Among the services, only the Marine Corps median is lower. The Navy median is also lower than the federal median.
This post uses the U.S. Sentencing Commission's records of 3,243 people sentenced in federal court in fiscal years 2016 to 2025, compared with court-martial results from this site's Military Trial Results data (updated November 2, 2026). Acquittals and dismissals come from a second source, the Federal Judicial Center's records of 753,808 federal defendants whose cases ended in fiscal years 2016 to 2025. It is part of the Federal Prosecution Analysis series, which builds on Military Moves Toward Sentencing Guidelines to Mirror the Federal System. How the numbers were built: How the Federal Comparison Data Was Built.
Navy Murder Sentences
Of the 12 Navy convictions, 11 had a sentence that included confinement (92%). A quarter of the sentences were 119.9 months or more, and 1 was confinement for life.
The Navy group includes officers. Officers convicted numbered 2, and 2 were dismissed. Of the 10 enlisted members convicted, 7 received a punitive discharge (70%): 6 dishonorable discharges and 1 bad-conduct discharge.
| Navy courts-martial | Federal court, FY2016–FY2025 | |
|---|---|---|
| Convictions or people sentenced | 12 | 3,243 |
| Sentenced to confinement or prison | 92% | more than 99% |
| Median confinement or prison | 95.9 months | 292 months |
| A quarter received this or more | 119.9 months | 470 months |
| Pleaded guilty | 6 of 12 with a plea recorded (50%) | 77% |
| Mandatory minimum applied | See the caveats | 44% |
Which Court-Martial Level Heard the Cases
A general court-martial heard 10 of the 12 Navy cases (83%). That is the highest trial level, and it is a lower share than in the Army and Air Force groups, where every case was at that level.
The other 2 cases were at a lower level. The records do not show whether trial level affected the sentences.
Guilty Pleas and Contested Cases in the Navy
A plea was recorded for all 12 convictions, and 6 were guilty pleas (50%). The median confinement was 119.9 months after a guilty plea, based on 5 cases.
In contested cases that ended in conviction, the median was 33 months, based on 5 cases. Trials in 2016 to 2019 had a median of 63 months, based on 6 cases, and trials in 2020 to 2025 had a median of 113.9 months, based on 4 cases.
Federal Murder Sentences
In fiscal years 2016 to 2025, the Sentencing Commission data lists 3,243 federal murder sentences under §2A1.1 (first degree) or §2A1.2 (second degree). Prison terms were imposed in 3,239, and life sentences in 683.
Terms of 470 months or more were given to the longest quarter, and terms of 180 months or less to the shortest quarter. Mandatory minimums applied in 1,434 cases (44%).
Federal Pleas and Trials
Federal court had 2,482 guilty pleas among 3,243 people (77%) and 761 convictions after trial. Median prison terms were 240 months after a plea and 470 months after a trial.
The Navy plea share of 50% is lower than the federal share. In the Navy, contested cases had the lower median, and in federal court trials had the higher median.
Comparing the Services
For the others, the Army median was 215.9 months (14 convictions), the Air Force median was 287.8 months (10), and the Marine Corps median was 56.5 months (4).
Counts this small make the service medians unstable.
| Service | Convictions, 2016–2025 | With confinement | Median confinement | Punitive discharge (enlisted) | Guilty pleas (where recorded) |
|---|---|---|---|---|---|
| Army | 14 | 100% | 215.9 months | 79% | 77% |
| Air Force | 10 | 100% | 287.8 months | 100% | 2 of 6 |
| Navy | 12 | 92% | 95.9 months | 70% | 50% |
| Marine Corps | 4 | 3 of 4 | 56.5 months | 3 of 3 | 1 of 3 |
What the Records Cannot Show
Navy sentences are as adjudged at trial, before any clemency or appeal. Federal terms are those imposed, not time served. Federal supervised release, fines, and restitution have no counterpart in the court-martial fields.
The records do not show the facts of any case or the reasons for a sentence. Federal criminal history data has no court-martial counterpart.
How We Counted
Navy courts-martial with trial dates in 2016 to 2025 ending in a conviction for murder (Article 118) (12). Federal: 3,243 people sentenced under guideline §2A1.1 (first degree murder) or §2A1.2 (second degree murder), fiscal years 2016 to 2025 (U.S. Sentencing Commission).
Federal fiscal years run from October 1 to September 30. No person, judge, or lawyer is identified in any of these records.
What to Keep in Mind
Who is in each set of numbers. The federal sentencing numbers come from the U.S. Sentencing Commission. They count only people who were convicted and sentenced in federal district court. People whose cases were dismissed or who were acquitted are not in them. The military numbers come from court-martial results, which include acquittals. To compare acquittal or dismissal rates, the federal side uses a different source: the Federal Judicial Center's case data, which counts every defendant whose case ended.
Different cases reach each system. Federal prosecutors bring a narrow set of cases. In fiscal year 2024, immigration and drug trafficking cases were 59% of everyone sentenced in federal court (36,664 of 61,678). Many crimes that the military prosecutes, such as most assaults, most sexual assaults between adults, and drug use, are usually state crimes for civilians and reach federal court only in special situations, such as on federal land or in Indian Country. A federal case and a court-martial for the same crime can involve different kinds of facts.
Time periods. Federal numbers are by federal fiscal year (October 1 to September 30), based on the sentencing date. The military numbers are by trial date. Neither source has the date of the offense, so a change in law shows up in either data set gradually.
Offense categories do not line up exactly. Each comparison uses a federal offense group chosen to match the military article as closely as possible (see the crosswalk). Some matches are close; others are partial. The post says which federal guideline or statute was used and why it is not an exact match.
No parole in federal prison; credit for good conduct. Federal prison has no parole for crimes committed on or after November 1, 1987. A federal prisoner can earn up to 54 days of good conduct credit for each year of the sentence the judge imposed, which is about 15%. Some federal prisoners can also earn First Step Act time credits, but many offenses make a person ineligible. The numbers in this post are the sentences judges imposed, not the time people actually served.
Military confinement credit and parole. For military sentences adjudged after 2004, good conduct time is 5 days for each month of confinement, about 16%. Military prisoners can also earn up to 8 more days a month for work and programs and up to 2 days a month for special acts, with a limit of 15 days a month in total. Military prisoners can be considered for parole by their service's clemency and parole board. The military numbers in this post are the confinement adjudged at trial, not the time served.
Military sentences include punishments federal sentences do not. A court-martial sentence can include a punitive discharge (bad-conduct discharge, dishonorable discharge, or dismissal for officers), reduction in rank, and forfeiture of pay. These have no federal counterpart. A comparison of months of confinement leaves them out. A short confinement term combined with a dishonorable discharge is a heavier sentence than the months alone show.
Federal supervised release. Most federal prison sentences are followed by a term of supervised release that the judge sets as part of the sentence. A person who violates it can be sent back to prison. A court-martial cannot sentence anyone to supervision after release. Military parole and mandatory supervised release are decided later by a board, not by the judge at trial.
Who decides the sentence, and under what rules. Federal judges sentence every federal case. They must calculate the Sentencing Guidelines range, which is advisory, and must impose any mandatory minimum the statute requires unless an exception applies. In courts-martial, the accused could choose sentencing by members until the rules changed. For cases in which every guilty finding is for an offense committed after December 27, 2023, a military judge sentences alone, within sentencing parameters. Courts-martial tried in 2024 and later include both old-rule and new-rule cases, and the data cannot tell them apart.
How life sentences and "time served" are counted. In the federal numbers, a life sentence is counted as 470 months, and any other sentence longer than 470 months is counted as just under 470 months. A sentence of "time served" is counted as one day (0.03 months). Averages are affected by these rules; medians much less.
