General Dynamics Pension Lump Sum vs. Annuity: A 2026 Guide for GD Employees

General Dynamics is one of the largest U.S. defense and aerospace contractors, with approximately $14 billion in pension plan assets as of recent annual filings and multiple qualified defined-benefit plans covering current and former employees across its four major business segments: Marine Systems, Aerospace (Gulfstream), Combat Systems, and Information Technology (GDIT). In 2025, General Dynamics completed two pension risk transfers totaling approximately $1.22 billion — a $673 million transaction announced in June 2025 and a $550 million transaction announced in July 2025 — transferring those obligations to insurance companies and ending PBGC federal insurance for affected participants.¹ For GD employees and retirees evaluating the lump-sum vs. annuity decision, these transfers change the risk analysis, the counterparty exposure, and the reasoning behind choosing to take the lump sum and move it to an IRA rather than leaving it as an annuity with an insurer.

General Dynamics' 2025 pension risk transfers: what you need to know

In 2025, General Dynamics executed two separate pension risk transfer transactions, the standard mechanism by which large employers reduce pension obligations by purchasing group annuity contracts from insurance companies.¹

• First transaction (June 2025): General Dynamics announced the transfer of approximately $673 million in pension plan liabilities to an insurance company. Participants whose benefits were included in this transfer received written notification from GD or the insurer.
• Second transaction (July 2025): General Dynamics transferred an additional approximately $550 million in pension liabilities. Benefits for affected participants are now administered by the purchasing insurer.

Together these transactions total approximately $1.22 billion in transferred obligations — a meaningful reduction in GD's total pension liability, though a minority of its roughly $14 billion in total plan assets.

The legal consequence for affected participants is the same in every pension risk transfer: once obligations transfer to an insurance company, PBGC federal insurance coverage ends entirely for that participant group. Monthly payments continue uninterrupted — the insurer takes over exactly where GD left off — but the backstop shifts from the PBGC (which covers up to $7,789.77/month at age 65 in 2026)² to the purchasing insurer's own financial reserves and applicable state insurance guaranty funds. Most states provide guaranty coverage of $250,000 or more per insurer per insured, which is not equivalent to PBGC protection for participants with annuities exceeding that threshold.

To put the 2025 GD transactions in context with major peer employers:

GD's transfers are smaller in absolute dollar terms than IBM, AT&T, or Verizon — but the pattern matters. Companies that execute one PRT frequently execute more as they reduce pension balance-sheet risk over time. Employees with large accrued annuities near or above the $7,789.77/month PBGC cap have the strongest economic argument for taking the lump sum now, before additional transfers shift more of the remaining balance into state guaranty fund territory.

General Dynamics' multi-division pension structure

Unlike some employers that operate a single large qualified pension plan, General Dynamics operates multiple qualified defined-benefit pension plans across its business segments, reflecting decades of acquisitions and the distinct labor markets of defense shipbuilding, aerospace manufacturing, and information technology.

Based on GD's annual filings, the company has operated as many as eleven qualified defined-benefit pension plans covering employees across different business units and workforce categories:

• Marine Systems: Electric Boat Corporation (nuclear submarines — Virginia class, Columbia class) and Bath Iron Works (surface ships — destroyers) both have significant legacy defined-benefit plans and large union workforces. Union pension mechanics at these facilities may differ from the salaried plans; union employees should consult their collective bargaining agreement and plan Summary Plan Description.
• Aerospace — Gulfstream: Gulfstream Aerospace (acquired 1999) operates under a separate employer umbrella and may maintain distinct plan documents from the broader GD pension programs.
• Combat Systems: Tank and armored-vehicle manufacturing facilities (Land Systems, Ordnance and Tactical Systems) have their own employee populations with pension benefits that may be governed by separate plan documents.
• Information Technology — GDIT: General Dynamics Information Technology serves federal government clients. Some GDIT employees may be covered under different retirement structures, particularly for contracts that involve successor plan obligations under Department of Labor Service Contract Act (SCA) rules.

The practical implication: your pension benefit, your lump-sum eligibility, and your distribution options depend on which specific plan covers your employment — not simply on being a "GD employee." Before modeling numbers or submitting a distribution election, obtain your current pension benefit statement and identify the plan name on the document. The Summary Plan Description for your specific plan is the controlling legal document for your rights and options.

How General Dynamics calculates your lump sum: IRS §417(e) segment rates

For employees and former employees eligible for a lump-sum distribution, the lump-sum amount is the actuarial present value of your accrued monthly annuity benefit, discounted using IRS §417(e)(3)(D) minimum present value segment rates.³ This is the same three-segment methodology used by virtually every large corporate defined-benefit plan.

The structure:

• Segment 1 applies to the first five years of projected annuity payments (near-term cash flows, discounted at the lowest rate).
• Segment 2 applies to years 6 through 20 (intermediate-term cash flows).
• Segment 3 applies to years 21 and beyond (long-dated cash flows, discounted at the highest rate).

Higher segment rates compress the lump sum because future payments discount to a smaller present value. Lower rates expand it. This inverse relationship means your retirement date — and specifically which month's rates your plan uses to set offers — can materially change the dollar amount.

Many large corporate plans use November segment rates to determine lump sums for benefit commencements throughout the following calendar year (a common "look-back" structure). November 2025 segment rates were approximately 4.07%, 5.15%, and 6.01% for Segments 1, 2, and 3 respectively.³ These are significantly higher than the near-zero rates of 2020–2021, meaning current lump-sum offers are materially smaller than they would have been for the same underlying benefit four years ago.

To illustrate: a $4,500/month straight-life annuity might have generated approximately $1.1 million as a lump sum in 2021. At November 2025 rates, the same annuity might generate $700,000–$870,000 — a gap of $230,000–$400,000 from the same accrued benefit, driven entirely by the rate environment.

Your plan's specific look-back month and "stability period" (how long one set of rates applies) are defined in your Summary Plan Description. Verify these details before targeting a specific retirement date to capture a particular month's rates — the timing benefit is only real if you're within the correct stability period. Use our lump-sum vs. annuity calculator and interest rate timing guide to model your actual numbers.

No COLA: fixed nominal payments erode purchasing power over time

GD's corporate defined-benefit pension annuity pays a fixed nominal dollar amount with no automatic cost-of-living adjustment. A $5,000/month payment in 2026 pays the same $5,000 in 2046. At 2.5% average annual inflation, that payment loses approximately 39% of its real purchasing power over 20 years — the equivalent of receiving roughly $3,050 in today's dollars by 2046.

Federal employees (FERS, CSRS) and military retirees receive annual COLA adjustments linked to CPI. Most corporate pensions, including GD's plans, do not. This makes the no-COLA penalty most acute for employees retiring at 55–62 with 25–35 years of retirement ahead. A lump sum invested in a diversified IRA can maintain real purchasing power above inflation — but at the cost of market risk and longevity risk. Use our COLA value calculator to put a dollar figure on what an annual adjustment would be worth given your benefit level and expected retirement horizon.

The 20% withholding trap — always use a direct rollover

If your GD plan issues the lump sum as a check payable directly to you rather than to an IRA custodian, federal law requires mandatory 20% income tax withholding. On a $700,000 lump sum, that is $140,000 withheld. To complete a tax-free rollover, you must deposit the full $700,000 into an IRA within 60 days — including $140,000 from other liquid sources you may not have available. Any shortfall is treated as a taxable distribution, and distributions before age 59½ may also trigger the 10% early-distribution penalty.

The correct approach: elect a direct rollover under IRC §402(c), instructing GD's plan administrator to transfer funds directly to your IRA custodian. No withholding applies on a properly executed direct rollover. Establish the receiving IRA before submitting your election so the custodian information is ready when GD processes the distribution. See our pension rollover to IRA guide for the step-by-step execution mechanics.

The SSIP 401(k) and the Rule-of-55 trap

Most GD employees carry a balance in the General Dynamics Savings and Stock Investment Plan (SSIP), the company's primary qualified 401(k) savings vehicle. The SSIP qualifies for the Rule of 55 under IRC §72(t)(2)(A)(v): if you separate from GD in the calendar year you turn 55 or later, you may take penalty-free withdrawals from the SSIP without waiting until 59½ and without establishing a 72(t) SEPP arrangement. This exception applies to qualified plan distributions from the employer's plan while that balance remains in the plan.

The trap: if you roll the SSIP balance to an IRA after separating from GD, the Rule-of-55 exception does not transfer. Once the money moves to an IRA, withdrawals before age 59½ face the standard 10% early-distribution penalty (unless you qualify for a different exception or establish a SEPP). Two consequences:

• If you need income between 55 and 59½: do not roll the SSIP to an IRA until you have confirmed you won't need penalty-free access in that window. Keep the SSIP in place and draw penalty-free under Rule of 55. You can roll to an IRA later — at 59½ or when convenient — without penalty.
• If you're 59½ or older and don't need early access: rolling to an IRA typically provides better investment flexibility, no required minimum distribution on Roth conversions, and simpler beneficiary planning. In that case, also evaluate the Roth IRA conversion window — large SSIP balances generate future RMDs that can spike IRMAA surcharges.

The pension lump-sum decision and the SSIP rollover decision are separate evaluations. They interact primarily through income bracket management in the year of each rollover — not through the benefit calculation itself. Evaluate them independently.

Five questions that determine your decision

1. Were you included in the 2025 pension risk transfers? If you received a letter from GD or an insurance company indicating your benefits were transferred, your annuity is now backed by state guaranty fund protections rather than PBGC. For benefits near or above $7,789.77/month — or for participants in states with guaranty limits under $250,000 per insurer — the lump sum eliminates insurer counterparty risk by moving funds into your own IRA.
2. What is the implied yield of your annuity? Divide your expected annual annuity payment by the lump-sum offer. If the ratio implies a 5% or higher annual return just to match the annuity's lifetime cash flows, the annuity typically wins for longevity purposes unless you can invest consistently above that threshold. Use our break-even calculator with your actual numbers to see which age the lump sum catches the annuity cumulatively.
3. Which specific GD plan covers your benefit? Multi-division structure means your lump-sum eligibility, survivor election options, and distribution mechanics depend on which plan you participated in — not just your employer name. Verify with your benefit statement before modeling any specific election.
4. What is your survivor situation? A straight-life annuity stops at your death. Under ERISA §205, married participants must have their spouse's written consent to waive the qualified joint-and-survivor annuity (at least 50% surviving benefit). The J&S reduction is typically 10–15% per month for a 50% survivor benefit. Modeling whether life insurance or the J&S election is more cost-effective requires an actuarial comparison based on your age gap and health history. See our joint-and-survivor election guide.
5. Do you need pre-59½ income from the SSIP? Separate from the pension decision, but critical. If yes, leave the SSIP in the qualified plan for Rule-of-55 access — do not roll it to an IRA before 59½.

After the rollover: RMDs, Roth conversions, and IRMAA

A GD lump sum rolled to a traditional IRA enters the required minimum distribution regime under SECURE 2.0. RMDs begin at age 73 (born 1951–1959) or age 75 (born 1960+), calculated annually from the IRS Uniform Lifetime Table.⁴ For a $750,000 IRA, the first RMD at age 75 is approximately $750,000 ÷ 24.6 ≈ $30,488 — fully taxable as ordinary income. By age 85 (divisor ~14.8), the same original balance, if growing at approximately 5% annually, could generate RMDs exceeding $65,000/year.

Combined with any retained GD annuity income and Social Security, these RMDs can push modified adjusted gross income above the 2026 IRMAA Tier 1 threshold of $109,000 single / $218,000 MFJ, adding $625–$2,625 in annual Medicare Part B and D surcharges per beneficiary.⁴

Key post-rollover strategies:

• Roth conversion window: Retiring at 58–64 with RMDs not beginning until 73 or 75 creates 9–17 years to convert traditional IRA dollars to Roth at 22–24% rather than 32–35% under forced RMDs. Use our Roth Conversion Optimizer to model annual conversion amounts given your pension annuity income and Social Security timing.
• QLAC to defer RMDs: A Qualified Longevity Annuity Contract purchased inside the IRA — up to $210,000 in 2026 per IRS Notice 2025-67 — is excluded from RMD calculations until age 85, deferring that portion's distributions and reducing near-term IRMAA exposure.⁴
• QCD strategy after 70½: Qualified Charitable Distributions up to $111,000/year (2026) satisfy RMDs without adding to taxable income — an efficient combination of charitable giving and IRMAA management.
• Asset allocation rebalance: Your GD pension annuity (whether kept or exchanged for a lump sum) functioned as a fixed-income-like asset in your overall portfolio. After rolling to an IRA and eliminating the guaranteed income stream, you can rationally shift your investable assets toward a higher equity allocation — particularly if Social Security and any retained annuity income together cover core living expenses. This is the "pension as bond" framing that often leads to underweighting equities when a retained annuity already provides bond-like stability.
