What Portsmouth Submarine & Maritime Association does
Mission
To educate the public about the maritime history of the piscataqua river basin and the significance of the portsmouth naval shipyard and the u.s. Navy's submarine service. Its most important activity is the display of a submarine, former uss albacore, and associated museum.
As stated on its FY2025 Form 990.
Programs
The former uss albacore is situated in a dry basin in albacore park where the general public can enter and walk through it, touch and operate equipment and listen to audio explanations at numerous locations inside and outside the vessel. A museum building displays items peculiar to uss albacore, the u.s. Submarine force in general, and the local maritime region. Attendance at the park in 2025 was 37,112 persons. The park was the site for several major outside displays by organizations promoting stem activities and careers.

A memorial garden is located within the park with monuments displaying the names of submarines lost in world war ii including the crew of the current submarine's namesake, uss albacore (ss218). Most visitors to the park also visited the garden.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2023 to 2024, from $2.0M to $2.7M (+39%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2017 11% · 2018 6% · 2019 0% · 2020 49% · 2021 7%. Grants only. Government contracts and fees sit inside program revenue.
6% of PORTSMOUTH SUBMARINE & MARITIME ASSOCIATION’s revenue is contributions — more earned-revenue than three-quarters of its peers (64% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 6 of the last 9 reported years ran a deficit.

Who funds it, year by year
2019 → 2023: the base broadened from 1 funder to 3 funders, grant income rose $25k → $38k.
2 of 6 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 93% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

How concentrated its funding is
PORTSMOUTH SUBMARINE & MARITIME ASSOCIATION leans on a few funders — its largest provides 93% of grant income and the top three 99%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
94% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund PORTSMOUTH SUBMARINE & MARITIME ASSOCIATION.
Largest funder’s share by year: 2019 100% · 2020 100% · 2021 51% · 2022 100% · 2023 95% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
93% of PORTSMOUTH SUBMARINE & MARITIME ASSOCIATION's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $111k that is directly attributable, 92% of it comes from funders outside New Hampshire, across 3 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.5M arriving through sponsors registered in 2 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
