Aerospace and Defense Legal Work: Venture Work at 3.1 Times the Market

A general counsel comparing aerospace and defense law firms this year is buying into a sector whose legal work has changed shape, not only size. Sartori & Partners data show venture and growth financings on 11.6% of aerospace and defense deals in the 12 months to October 2026, against 3.8% across all deals. That is 3.1 times the market rate, in a sector better known for securities offerings and acquisitions. It sits on top of the fastest deal growth of any sector in our records: 651 deals in the latest settled 12 months, against 432 a year earlier. The practical result is a panel question. The firm that runs a defense company's offering or acquisition is not always the firm that runs its private funding round.

Venture and growth deals numbered 75 in the sector over 12 months, or 11.6% of its deals. Across the whole market the same type is 3.8% of deals, so aerospace and defense buys this work at 3.1 times the market's rate. Each type share counts deals of that type against every deal in the sector, typed or not, so the shares are read one at a time and never summed.

Neighboring sectors put the figure in proportion. Technology and software, where funding rounds are routine, carries the type on 15.3% of its deals, above the aerospace and defense rate. Electronics and semiconductors, the other hardware sector buyers often compare with, sits at 5.7%, so the aerospace and defense share is 2.0 times the chip sector's. Aerospace and defense now raises money more like a software sector than like a classic hardware one.

For a defense, space or drone company raising private capital, the financing counsel on the panel needs venture experience, not only public-offering experience. Ask a shortlisted firm which priced rounds its team closed for hardware companies in the past year, and which partner negotiates investor terms and side letters.

Venture work is the distinctive share, not the largest one. Capital markets deals are 34.9% of aerospace and defense deals against 25.7% market-wide, and M&A is 27.5% against 19.3%. Disputes and investigations run the other way, on 8.5% of the sector's deals against 25.0% across the market, a gap of 16.5 points.

The practice records agree. In Sartori & Partners deal records, corporate and M&A lawyers worked on 42.2% of aerospace and defense deals, against 23.3% of all deals, and capital markets lawyers on 36.5% against 26.4%. Banking and finance lawyers sit at the market rate, 6.4% against 6.3%. Where a value is disclosed, on 29.5% of sector deals, the median deal is $500 million, against $250 million in technology and software.

So the venture work arrives beside a heavy load of securities and acquisition work, not in place of it. A company that expects to raise privately now and list or sell later gains from one firm whose team covers each stage, rather than a new adviser at every step.

Volume moved as fast as the mix. Aerospace and defense deals rose 50.7% between the two latest settled 12-month windows, from 432 to 651. All deals rose 10.6% over the same windows, so the sector grew 4.8 times as fast as the market. Electronics and semiconductors rose 33.9%. Technology and software held flat (+4.6%), and industrial manufacturing held flat (+3.2%).

The bars are read for direction only, because earlier years rest on fewer reporting firms. From January to October 2026 the sector logged 557 deals, against 473 in the whole of 2025. The settled windows carry the comparison, and on them aerospace and defense moved faster than each neighbor named here.

Fast growth tightens capacity. A sector adding deals at this pace stretches the partners who know its export and security rules, so agree staffing before a round or filing date is fixed, and ask for the names of the associates who will do the daily work.

Each city share counts the sector's deals, among those with a known lawyer location, that had lawyers working on them from that city; one deal can count in several cities, so the shares overlap. New York comes first, with lawyers there on 42.3% of aerospace and defense deals. Washington, DC is second at 26.7%, ahead of London at 17.3%.

The Washington figure is what sets the sector apart. Lawyers in Washington worked on 19.6% of technology and software deals, 7.1 points lower. They worked on 14.9% of industrial manufacturing deals, which puts the aerospace and defense share at 1.8 times the industrial rate, and on 15.7% of electronics and semiconductor deals.

For a company whose deals touch government customers or foreign investors, the Washington lawyers are part of the transaction, not a later check. When a firm pitches, ask whether its Washington lawyers sit on the deal team from the term sheet, and how they split the hours with the corporate team in New York or elsewhere.

Latham & Watkins advised on the most aerospace and defense deals in 12 months, in the 41-60 band. Davis Polk & Wardwell, Wilson Sonsini Goodrich & Rosati, Kirkland & Ellis and Sheppard, Mullin, Richter & Hampton follow, all in the 21-40 band, so their order says little about volume. Against the market-wide list the sector ranking shifts: Wilson Sonsini Goodrich & Rosati, Sheppard, Mullin, Richter & Hampton, Goodwin Procter and Fenwick & West rank in the aerospace and defense top 10 but not in the top 10 across all deals. The other six appear on both lists.

Do not read a sector rank as a venture credential. Bands count deals of every type, so a firm high on the list may owe its place to offerings or acquisitions, and the bands are wide: the five firms sharing the 11-20 band are close in volume. Ask each firm on a shortlist for its aerospace and defense venture deals in particular, and compare the partners it names.

Build the panel around three kinds of work, not one. Capital markets and M&A still carry the largest shares of aerospace and defense deals, at 34.9% and 27.5%, so the lead firm needs depth in both. Add venture financing as a named requirement: with the type on 11.6% of sector deals, a company raising private capital should confirm that its team has run priced rounds and growth equity deals, not only offerings.

Then test the Washington side. Lawyers there worked on 26.7% of the sector's deals, against 19.6% in technology and software, so ask how a firm's Washington lawyers join the deal and when. Plan for capacity as well: sector deals rose 50.7% in a year against 10.6% for all deals, so open firm conversations before a round or filing date is set.
