South Korea placed a parts order worth $1.2 billion to upgrade its Boeing Apache attack helicopters.
At the same time, South Korea will spend $3 billion to buy brand-new Lockheed Sikorsky Seahawks.
The Lockheed deal is bigger -- and also more profitable for the defense stock.
Brief bouts of fighting broke out in the Strait of Hormuz this week, with Iran apparently launching drone attacks on commercial shipping, U.S. Navy warplanes responding, and Iran responding to that with an attack on Kuwait. Nevertheless, both sides to the conflict continue to act as if the ceasefire remains intact.
Meanwhile, in South Korea, the government is preparing for the next conflict.

As the U.S. State Department advised Congress earlier this month, the government of South Korea has made requests to purchase two separate batches of military helicopters and equipment from Boeing (NYSE: BA) and Lockheed Martin (NYSE: LMT), respectively.
From Boeing, the Koreans wish to purchase eight AN/APG-78 fire-control radar (FCR) systems, eight Longbow FCR Radar Electronic Units (REUs), 40 AN/ARC-231A VHF/UHF ("very high frequency" and "ultra high frequency") radios, and a whole series of related gear. This equipment will be installed to upgrade its fleet of 36 existing AH-64E Apache attack helicopters, with 36 more on order.
Just as you'd expect for the builder of the Apache, Boeing was named principal contractor on this arms deal and stands to win $1.2 billion in revenue if Congress approves the sale.
In a separate and much larger deal, South Korea has requested permission to purchase 24 MH-60R Sikorsky Seahawk multimission helicopters. Among the related equipment involved in this purchase are 24 Airborne Low Frequency Sonar (ALFS) systems -- indicating that the helicopters will be used primarily for anti-submarine missions.
Lockheed Martin, which acquired Sikorsky from the company then known as United Technologies more than a decade ago, will serve as the principal contractor on this $3 billion defense contract.
Add 'em up: That's $4.2 billion worth of American helicopters and parts heading to South Korea.
Granted, Congress must approve (or more precisely, fail to pass a "joint resolution of disapproval" of) these arms deals for them to go through. A resolution of disapproval has happened only once in the last 50 years, and never in the last 30, according to a report from the Congress-focused newspaper Roll Call. Statistically speaking, both the Boeing and the Lockheed Martin arms sales are all but guaranteed to sail through Congress -- which means it's probably safe for Boeing and Lockheed investors to go ahead and start counting up revenue and profits today.
In the case of Boeing, $1.2 billion in helicopter parts will be run through the Boeing Defense, Space & Security division, colloquially known as "BDS." Data from S&P Global Market Intelligence shows recent improvements in BDS. Although the division has been losing money since 2022, losses that used to number in the billions of dollars fell to just $128 million last year -- and turned positive in the first quarter of 2026 with a $233 million operating profit, up 50% year over year.
At Lockheed Martin, helicopter sales aren't housed in its marquee Aeronautics division, but rather in a special segment designated Rotary and Mission Systems (RMS). The good news for Lockheed Martin investors is that this business is more profitable for Lockheed than BDS currently is for Boeing.
S&P Global data show that RMS earned $1.3 billion in operating profit on $19.7 billion in sales last year, resulting in an operating profit margin of 6.7%. That's still not a great number for Lockheed Martin, which earned operating margins of over 10% for the company as a whole in 2025. Still, Boeing's operating margin in Q1 was only 3.1%, and it was negative last year.
Even better news: In Q1 2026, the profit margin in Lockheed's RMS business expanded to 9.2%.
RMS may not quite be firing on all cylinders yet. However, it is improving, and a 9.2% profit margin on $3 billion in Sikorsky sales should still generate nearly $277 million in operating profit for Lockheed on its contract.
By comparison, even if Boeing can maintain its current 3.1% margin at BDS, its $1.2 billion Apache parts sale might generate as little as $37 million profit for the company -- just 1.1% of the $3.3 billion operating profit Boeing earned over the last 12 months.
Combine the size of the potential profits from these deals with the fact that Boeing stock costs 90 times trailing earnings today, while Lockheed looks like a relative bargain at just 26 times earnings, and the choice is clear: Lockheed Martin stock is the better buy.

Four leading AI models discuss this article
"The $3B Lockheed contract adds limited near-term EPS impact once realistic margins and multi-year timing are applied."
The article frames Lockheed's $3B Seahawk deal as clearly superior due to higher RMS margins (now 9.2%) versus Boeing's thin 3.1% BDS margin. Yet both contracts remain State Department requests subject to congressional review, with revenue likely spread over multiple years. At roughly 15% of annual RMS sales, the Lockheed order is material but not transformative, while Boeing's Apache upgrade could accelerate its defense recovery. Geopolitical timing around Hormuz incidents adds uncertainty to approval speed. Investors should weigh execution risks and backlog conversion rates rather than headline dollars alone.
Congress has rarely blocked such sales, but escalating U.S.-China tensions could prompt South Korea to diversify suppliers or delay payments if regional priorities shift.
"LMT is the better near-term profit play on this deal, but BA's BDS turnaround is the more important structural story the article undersells."
The article frames this as a clean LMT win over BA, but that's misleading. Yes, LMT's RMS margin (9.2% Q1) beats BA's BDS (3.1%), and yes, $277M profit beats $37M. But the article ignores: (1) BA's BDS is in recovery mode—losses shrinking from billions to $128M annually, now positive in Q1. That's the real story. (2) LMT's 26x P/E isn't cheap; it's priced for margin expansion. (3) Both deals face Congressional approval risk that's statistically low but non-zero. (4) South Korea's helicopter spending signals regional escalation (North Korea, China), which could drive future orders—but timing and magnitude are speculative.
If BA's BDS division continues its margin recovery trajectory, the $1.2B Apache deal could generate $50-80M profit, not $37M. Meanwhile, LMT's 9.2% margin may not stick if defense budgets tighten or supply-chain costs rise—the article cherry-picks Q1 data without showing trend stability.
"Lockheed Martin's margin expansion in the RMS segment makes it a superior defense play over Boeing, which continues to struggle with low-margin, high-risk defense execution."
While the headline focuses on the $4.2 billion order, investors should look past the headline revenue and focus on margin expansion. Lockheed Martin’s Rotary and Mission Systems (RMS) segment hitting a 9.2% operating margin in Q1 2026 is the real story, signaling that the Sikorsky integration is finally yielding efficiency. Conversely, Boeing’s Defense, Space & Security (BDS) remains a volatile turnaround play; a 3.1% margin on a $1.2 billion contract is negligible for a company with its current debt load. Lockheed is the clear winner here, but the market is already pricing in this 'safe' defense spending, leaving limited upside unless geopolitical tensions in the Indo-Pacific trigger a larger, sustained procurement cycle.
The thesis assumes these contracts are highly profitable, but fixed-price defense contracts are notoriously susceptible to cost overruns and supply chain inflation that can quickly erode those 9.2% margins.
"Lockheed Martin's RMS-driven profits from the Seahawk orders, plus a durable defense-budget backdrop, imply a more reliable, long-run upside for LMT than the headline $4.2B deal suggests."
Bottom line: the $4.2B headline belies execution risk and a mixed profitability read. The article assumes instant approvals and applies RMS margins to a $3B contract, but real profits depend on life-cycle maintenance, spares, and potential cost overruns. A sizable part of the upside rests on US defense budgets and steady Seahawk/Apache service work, not just the initial sale. The comparison of Boeing’s 90x vs Lockheed’s 26x P/E seems exaggerated given cyclicality and margin mix. Missing context includes long-run budgets, potential delays, and competition in a crowded, politically sensitive market.
Even with approvals, the profitability story rests on aggressive assumptions: life-cycle costs, maintenance, and spares will eat into margins. There is execution risk in integration, and defense budgets can wobble, potentially delaying or altering the contract economics.
"Fixed-price inflation risks threaten LMT's reported margins as much as BA's recovery narrative."
Gemini claims Sikorsky integration is finally driving sustainable 9.2% RMS margins, yet both LMT and BA operate under fixed-price terms where titanium and electronics inflation can erase gains before delivery. The $3B Seahawk order equals roughly 15% of annual RMS revenue but conversion depends on spares and sustainment cycles that rarely match initial margins. South Korea's budget timing amid its own procurement priorities adds another delay vector neither side has quantified.
"Fixed-price defense margins are fragile; a 15% commodity cost shock wipes out Boeing's entire contract profit, yet no panelist has modeled this scenario."
Claude and ChatGPT both flag BDS margin recovery as underappreciated, but neither quantifies the risk: BA's 3.1% margin assumes no supply-chain shocks or contract restructuring. Fixed-price contracts in aerospace routinely compress 2-3% when labor/materials spike. If titanium costs spike 15% mid-delivery (plausible given geopolitical supply constraints), that $37M profit evaporates. Grok's inflation vector is the real story—not the headline dollars.
"Boeing's thin margins make them structurally incapable of absorbing the supply-chain shocks that Lockheed's stronger balance sheet can mitigate."
Claude, your focus on BA's margin recovery ignores the structural debt burden. While you correctly identify the risk of titanium price spikes, you overlook the opportunity cost of Boeing’s capital allocation. Lockheed’s 9.2% margin isn't just about efficiency; it's about a superior balance sheet that can absorb the supply-chain shocks you mention. Boeing’s 3.1% margin leaves zero room for error, making them a binary bet on execution, not a value play.
"Sustained margins depend on lifecycle maintenance profits; a 9.2% Q1 RMS margin may erode if inflation and sustainment costs spike."
Gemini, good eye on the 9.2% RMS margin, but a single-quarter print isn't a sustainable moat. Fixed-price defense work with inflation shock or supply-chain hiccups tends to compress margins 2-3 percentage points once sustainment dollars flow in. The real prize is lifecycle profits from maintenance and spares, not the initial sale. If titanium, electronics, or labor costs spike and backlog ramps under-delivery, Lockheed’s 9.2% could retreat toward the mid/high single digits.
While Lockheed Martin's $3B Seahawk deal appears superior due to higher margins, both deals face congressional approval risks and potential execution challenges. Investors should consider long-term budgets, potential delays, and competition in the market.
